Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
the antenna includes a radiation element and a feed element, and generally a half-wave element is used as the radiation element. The half-wave oscillator comprises two sections of radiating bodies which are symmetrically arranged, and has the advantages of simple engineering realization, space saving and the like, however, the working bandwidth of the half-wave oscillator cannot be too wide, and if the working bandwidth is too wide, the deviation of the antenna standing wave, the wave beam width, the gain and the like from the design values can be caused, so that in the related technology, the bandwidth of the half-wave oscillator is narrow, and the cost is high when the multi-band coverage is realized. In order to solve the above technical problem, an embodiment of the present invention provides a half-wave resonator, as shown in fig. 1, including: a first radiating arm 10 and a second radiating arm 20; the first radiating arm 10 and the second radiating arm 20 each include two segments of radiators arranged on a straight line and a connector arranged between the radiators, and the connector is used for disconnecting or connecting the two segments of radiators in the radiating arms; of the first and second radiating arms 10 and 20, the radiator near the other radiating arm is used for connecting with the feed unit 30; the radiator of the first radiating arm 10 is arranged symmetrically to the radiator of the second radiating arm 20. That is, the half-wave radiator includes 4 radiators and 2 connectors, the first radiator 101 and the second radiator 102 are disposed on the same straight line, the first connector 103 is disposed between the first radiator 101 and the second radiator 102 to constitute the first radiating arm 10, and the first connector 103 is used to disconnect the first radiator 101 from the second radiator 102 or connect the first radiator 101 to the second radiator 102; the third radiator 201 and the fourth radiator 202 are arranged on the same straight line, the second connector 203 is arranged between the third radiator 201 and the fourth radiator 202 so as to form the second radiating arm 20, and the second connector 203 is used for disconnecting the connection between the third radiator 201 and the fourth radiator 202 or connecting the third radiator 201 and the fourth radiator 202; the first radiator 101 and the fourth radiator 202 are symmetrically disposed (i.e., the first radiator 101 and the fourth radiator 202 are the same, and the first radiator 101 and the fourth radiator 202 are symmetrical in position), and the second radiator 102 and the third radiator 201 are symmetrically disposed (i.e., the second radiator 102 and the third radiator 201 are the same, and the second radiator 102 and the third radiator 201 are symmetrical in position), where the second radiator 102 is a radiator of the first radiating arm 10 close to the second radiating arm 20, the third radiator 201 is a radiator of the second radiating arm 20 close to the first radiating arm 10, and the second radiator 102 and the third radiator 201 are used for connecting to the feed unit 30. It should be understood that the length of the radiator is related to the operating frequency band thereof, and therefore, the length of the effective radiator of the radiation arm can be changed by disconnecting and connecting the connector, so that the operating frequency band of the radiation arm covers two operating frequency bands, thereby increasing the bandwidth of the half-wave radiator, for example, for a first radiation arm, when the first connector 103 connects the first radiator 101 and the second radiator 102, at this time, the first radiator 101 is connected with the feeding unit 30 through the second radiator 102, the effective radiator of the first radiation arm 10 is the first radiator 101 and the second radiator 102, and the operating frequency band is the first frequency band (it should be understood that the first frequency band corresponds to the lengths of the first radiator 101 and the second radiator 102); when the first connector 103 disconnects the first radiator 101 and the second radiator 102, only the second radiator 102 is connected to the feed unit 30, the effective radiator of the first radiating arm 10 is the second radiator 102, and the operating frequency band is the second frequency band (it should be understood that the operating frequency band corresponds to the length of the second radiator 102); for the second radiating arm, see the first radiating arm.
The radiator may be a metal radiator, and the metal radiator may be a printed vibrator or a die-cast vibrator. The length of the radiator can be flexibly set according to actual needs. Since the length of the radiator is related to the operating frequency band of the radiator, the length of the radiator can be determined according to the operating frequency band of the half-wave oscillator which needs to be designed. In the embodiment of the present invention, the two radiators of the first radiating arm 10 may be the same or different, and the two radiators of the second radiating arm 20 may be the same or different.
In the embodiment of the present invention, the included angle between the first radiation arm 10 and the second radiation arm 20 may be greater than or equal to 90 degrees and less than or equal to 180 degrees, for example, as shown in fig. 1, the included angle between the first radiation arm 10 and the second radiation arm 20 is 180 degrees (i.e., the first radiation arm 10 and the second radiation arm 20 are disposed on a straight line), or, as shown in fig. 2, the included angle between the first radiation arm 10 and the second radiation arm 20 is 90 degrees; still alternatively, referring to fig. 3, the angle between the first radiation arm 10 and the second radiation arm 20 is 120 degrees.
In the embodiment of the present invention, the states of the connectors in the two radiating arms may be different, for example, the first connector 103 connects the first radiator 101 and the second radiator 102, and the second connector 203 disconnects the third radiator 201 and the fourth radiator 202, at this time, the operating frequency band of the first radiating arm 10 is the first frequency band, and the operating frequency band of the second radiating arm 20 is the second frequency band. In order to improve radiation efficiency, the state of the connectors in the two radiating arms may be the same, that is, the state of the connector (i.e., the first connector 103) of the first radiating arm 10 is the same as the state of the connector (i.e., the second connector 203) of the second radiating arm 20, for example, the first connector 103 and the second connector 203 may both be in a connected state, at this time, the first radiator 101 is connected to the second radiator 102, the third radiator 201 is connected to the fourth radiator 202, and the operating frequency bands of the first radiating arm 10 and the second radiating arm 20 are both the first frequency band; alternatively, the first connector 103 and the second connector 203 may both be in an off state, at this time, the first radiator 101 and the second radiator 102 are in an off state, the third radiator 201 and the fourth radiator 202 are in an off state, and the operating frequency bands of the first radiating arm 10 and the second radiating arm 20 are both the second frequency band.
In the embodiment of the present invention, referring to fig. 4, the connector may be a switch, two ends of the switch are respectively connected to the two sections of radiators, and disconnection and connection of the switch are controlled according to a frequency band of a signal to be transmitted or received, so as to implement switching of a working frequency band of the half-wave vibrator. That is, one end of the first switch 103 is connected to the first radiator 101, and the other end is connected to the second radiator 102; one end of the second switch 203 is connected to the third radiator 201, and the other end is connected to the fourth radiator 202.
In the embodiment of the present invention, referring to fig. 5, the connector may be a reactance line, two stages of the reactance line are respectively connected to two radiators in the radiating arm, one stage of the first reactance line 103 is connected to the first radiator 101, the other pole of the first reactance line 103 is connected to the second radiator 102, one stage of the second reactance line 203 is connected to the third radiator 201, the other pole of the second reactance line 203 is connected to the fourth radiator 202, and whether the two stages of the reactance lines are connected or not is related to the frequency band of the signal input to the reactance line, in the embodiment of the present invention, the reactance line has the following characteristics: when the frequency of the signal input into the reactance line is in a first frequency band, the two stages of the reactance line are in a connected state, and when the frequency of the signal input into the reactance line is in a second frequency band, the two stages of the reactance line are in a disconnected state; that is, signals in the first frequency band may be transmitted between two stages of the reactance lines, and signals in the second frequency band may not be transmitted between two stages of the reactance lines. In this way, for the first radiating arm 10, when a signal input to the first radiating arm 10 is in the first frequency band, the signal may pass through the first reactance line 103, and thus be transmitted between the first radiator 101 and the second radiator 102, and the effective radiators are the first radiator 101 and the second radiator 102; when the signal input to the first radiating arm 10 is in the second frequency band, the signal cannot pass through the first reactance line, and the effective radiator is the second radiator 102; for the second radiation arm 20, the working principle thereof is referred to the working principle of the first radiation arm 10, and the detailed description thereof is omitted. The reactance line is adopted as a connector, so that disconnection and connection under different frequency bands can be realized, and because two-stage disconnection and connection of the reactance line are related to the frequency of a signal input to the reactance line, the signals in the first frequency band and the second frequency band can be simultaneously input to the first radiating arm 10, the signal in the first frequency band is transmitted through the first radiating body 101 and the second radiating body 102, and the signal in the second frequency band is transmitted through the second radiating body 102, so that the two frequency bands can be simultaneously covered.
In the embodiment of the invention, the reactance line can be a semi-rigid cable, and of course, the reactance line can also be made of other materials.
In the embodiment of the present invention, the signal sent to the first radiating arm 10 and the signal sent to the second radiating arm 20 may have the same frequency band and a phase difference of 180 degrees.
The embodiment of the invention provides a half-wave oscillator and a half-wave oscillator component, wherein the half-wave oscillator comprises: a first radiating arm and a second radiating arm; the first radiation arm and the second radiation arm respectively comprise two sections of radiators arranged on a straight line and a connector arranged between the radiators, and the connector is used for disconnecting or connecting the two sections of radiators in the radiation arms; in the first radiation arm and the second radiation arm, a radiator close to the other radiation arm is used for being connected with the feed unit; the radiating bodies of the first radiating arm and the second radiating arm are symmetrically arranged, in some implementation processes, each radiating arm of the half-wave oscillator comprises two sections of radiating bodies, the two sections of radiating bodies can be connected or disconnected, when the two sections of radiating bodies are disconnected, the effective radiating body of the radiating arm is one section, when the two sections of radiating bodies are connected, the effective radiating bodies of the radiating arm are two sections, and when the effective radiating bodies are one section and two sections, the radiation frequencies are different, so that the working frequency band of the radiating arm can cover the two frequency bands, the working bandwidth of the half-wave oscillator is increased, and the cost for realizing multi-band coverage is reduced.
Example two:
for a better understanding of the present invention, embodiments of the present invention are described with reference to more specific examples. Referring to fig. 6, a half-wave resonator according to an embodiment of the present invention includes: a first radiating arm 10 and a second radiating arm 20; the first radiating arm 10 and the second radiating arm 20 each include two segments of radiators arranged on a straight line and a reactance line arranged between the radiators; of the first and second radiating arms 10 and 20, a radiator close to the other radiating arm is connected to the feed unit 30; the radiator of the first radiating arm 10 is arranged symmetrically to the radiator of the second radiating arm 20. That is, the half-wave radiator includes 4 sections of radiators and 2 sections of reactance lines, the first radiator 101 and the second radiator 102 are arranged on the same straight line, the first reactance line 103 is arranged between the first radiator 101 and the second radiator 102, and two stages thereof are respectively connected with the first radiator 101 and the second radiator 102, thereby constituting the first radiation arm 10; the third radiator 201 and the fourth radiator 202 are disposed on the same straight line, the second reactance line 203 is disposed between the third radiator 201 and the fourth radiator 202, two stages of which are connected to a third radiator 201 and a fourth radiator 202, respectively, to constitute a second radiating arm 20, and, the first radiator 101 and the fourth radiator 202 are symmetrically disposed (i.e., the first radiator 101 and the fourth radiator 202 are the same, and the first radiator 101 and the fourth radiator 202 are symmetrically located), the second radiator 102 and the third radiator 201 are symmetrically disposed (i.e., the second radiator 102 and the third radiator 201 are the same, and the second radiator 102 and the third radiator 201 are symmetrically located), the second radiator 102 is a radiator of the first radiation arm 10 close to the second radiation arm 20, the third radiator 201 is a radiator of the second radiation arm 20 close to the first radiation arm 10, and the second radiator 102 and the third radiator 201 are connected to the feed unit 30.

Assuming that the first frequency band is f1The second frequency band is f2The first frequency band pairThe wavelength is λ1The wavelength corresponding to the second frequency band is λ2Then f is2Greater than f1，λ1Greater than λ2，f2At [1.8f1，2.2f1]Length of the metallic radiator is lambda2/4, the spacing between two stages of reactive lines being less than λ2100, length: lambda [ alpha ]2/(2ε1/2) Wherein epsilon is the dielectric constant of the material for manufacturing the reactance line.
