the resonator unit 7 is arranged between the resonant layer dielectric substrate 6 and the top layer dielectric substrate 8;
the resonant network 3 includes: a microstrip line 301, a lower feed post 302, a first LC combination 303, and an upper feed post 304; the first LC combination 303 comprises at least one inductance and/or at least one capacitance, the LC combinations being connected in parallel on the microstrip line 301; the first end of the lower feed post 302 is connected to the first LC combination 303 on the microstrip line 301, and the second end passes through the underlying dielectric substrate 2 and extends to the antenna ground plane 1; the upper feed post 304 has a first end connected to the first LC combination 303 on the microstrip line 301 and a second end passing through the radiating layer dielectric substrate 4 and extending to the radiating patch 5.
The antenna ground layer 1 generally uses a metal sheet as the ground layer of the antenna.
The bottom dielectric substrate 2, the radiation layer dielectric substrate 4, the resonance layer dielectric substrate 6, and the top dielectric substrate 8 are PBE dielectric substrates, the multi-layer dielectric substrates form a main structure of the antenna, each dielectric substrate is divided into the bottom dielectric substrate 2, the radiation layer dielectric substrate 4, the resonance layer dielectric substrate 6, and the top dielectric substrate 8 based on different installation positions, and the installation positions of each dielectric substrate are shown in fig. 1.
Referring to fig. 2, the resonant network 3 includes: a microstrip line 301, a lower feed post 302, a first LC combination 303 and an upper feed post 304.
In specific practice, the microstrip line 301 has a "sun" shape structure as shown in fig. 2, the first LC combination 303 is disposed on three sides of the "sun" shape microstrip line 301 that are parallel, and the lower feeding post 302 and the upper feeding post 304 are disposed on the other two sides of the "sun" shape microstrip line 301 that are parallel.
Note that, the first LC combination 303 in this embodiment refers to an inductance (L) and capacitance (C) combination, and the first LC combination 303 in this embodiment may be a combination of 3 inductances, a combination of 3 capacitances, a combination of 2 inductances and 1 capacitance, or a combination of 1 inductance and 2 capacitances. Each component in the first LC combination 303 does not limit the setting position when setting, that is, if the first LC combination 303 is a combination of 2 inductors and 1 capacitor, when setting, the 1 capacitor may be sandwiched by the 2 inductors, or the 1 capacitor may be set on one side, and the 2 inductors may be set on the other side.
Note that the first end of the lower feeding post 302 and the first end of the upper feeding post 304 are disposed opposite to each other on the microstrip line 301. The lower feed post 302 and the upper feed post 304 in this embodiment are conventional feed posts in the art. The first end of the lower feed post 302 is connected to the first LC combination 303 on the microstrip line 301, and the second end passes through the underlying dielectric substrate 2 and extends to the antenna ground plane 1; the upper feeding post 304 has a first end connected to the first LC combination 303 on the microstrip line 301 and a second end passing through the radiation layer dielectric substrate 4 and extending to the radiation patch 5 to feed the radiation patch 5.
In the technical scheme in this embodiment, the feeding form between the radiating patch 5 and the antenna ground layer 1 is adjusted, a tuning network is added between the antenna ground layer 1 and the feeding end, the resonant network 3 includes a microstrip line 301 and a first LC combination 303, and the microstrip line 301 and the first LC combination 303 can generate a plurality of resonance points, so as to improve the working bandwidth of the phased array antenna.
When the beam scanning angle of the phased array antenna unit in the prior art reaches 60 degrees, coupling among units is too strong, so that gain deterioration is aggravated, the gain is reduced by 6dBi or more, and the limit scanning angle is about 65 degrees.
Based on this, the tendency of the antenna gain to drop steeply with an increase in the scan angle is alleviated in the present embodiment by improving the radiation patch 5.
The radiation patch 5 in the present embodiment is used as the radiation patch 5 of the antenna "lower layer", and the resonator unit 7 is used as the radiation patch 5 of the antenna "upper layer".
In specific practice, the resonant layer dielectric substrate 6 and the resonator unit 7 are at least one group;
the resonator unit 7 is disposed between the current layer resonance layer dielectric substrate 6 and the top layer dielectric substrate 8, or between the current layer resonance layer dielectric substrate 6 and the upper layer resonance layer dielectric substrate 6.
As the number of sets of the resonant layer dielectric substrate 6 and the resonator unit 7 increases, the antenna gain tends to decrease more sharply with increasing scan angle, but the cost is higher.
Referring to fig. 3, the resonator unit 7 includes: a polygonal resonant circuit 701, a loading capacitance combination 702 or a second LC combination disposed on the polygonal resonant circuit 701;
wherein the loading capacitor assembly 702 comprises at least one loading capacitor; the second LC combination includes at least one inductance, and/or at least one capacitance.
Note that, the second LC combination in this embodiment refers to an inductance (L) and capacitance (C) combination.
As shown in fig. 3, the polygonal resonant circuit 701 is a symmetrical structure with a pattern of an angular flower and a ground pattern, and the internal structure is matched with a loading capacitor or a second LC combination, because the resonator unit 7 in the embodiment is used as the radiation patch 5 of the "upper layer" of the antenna, the radiation patch 5 of the "upper layer" of the antenna can be designed as above, and the isolation between units is increased, so that the mutual coupling between units is reduced, and the trend that the gain is suddenly reduced along with the increase of the scanning angle is slowed down.
In fig. 3, the components disposed in the polygonal resonant circuit are taken as examples of the loading capacitors, and as shown in fig. 3, each loading capacitor in the loading capacitor group 702 is disposed on each side of the polygonal resonant circuit.
If the components provided in the polygonal resonant circuit are the second LC combination, the inductance and/or capacitance in the second LC combination are provided on each side of the polygonal resonant circuit 701.
It should be noted that, the second LC combination in this embodiment may be a combination of 4 inductors, a combination of 4 capacitors, a combination of 3 inductors and 1 capacitor, a combination of 1 inductor and 3 capacitors, or a combination of 2 inductors and 2 capacitors. The components in the second LC combination are not limited to the arrangement positions at the time of arrangement.
Referring to fig. 3, the resonator unit 7 further includes: a choke ring 703;
a choke 703 is provided around the polygonal resonant circuit 701.
In particular practice, the choke 703 is a square ring structure.
The choke 703 is also called a choke coil, and the choke 703 is an inductance element and mainly serves to control the direction and magnitude of current flowing. When a direct current or an alternating current flows through the choke coil 703, a reverse potential is generated due to the inductance effect thereof, and the change of the current is hindered, thereby achieving the effects of current limiting and suppressing high-frequency interference.
Referring to fig. 3, the resonant layer dielectric substrate 6 includes an upper layer of the resonant layer dielectric substrate 6 and a lower layer of the resonant layer dielectric substrate 6;
the resonator unit 7 is arranged between the upper layer of the resonant layer dielectric substrate 6 and the top layer dielectric substrate 8;
an air cavity 601 is arranged below the resonant layer dielectric substrate 6.
It should be noted that, in this embodiment, by disposing the air cavity 601 under the dielectric substrate 6 of the resonant layer, isolation between units can be better increased, mutual coupling between antenna units can be reduced, and a trend that gain decreases steeply with increasing scan angle can be slowed down.
In summary, the wideband phased array antenna unit with the composite structure in the embodiment widens the working bandwidth of the phased array antenna, and in specific practice, the working bandwidth can reach about 60%.
In specific practice, when the scanning angle of the broadband phased array antenna unit with the composite structure in the embodiment reaches 75 degrees, the gain is reduced by about 6dBi, no abrupt drop occurs, and the beam is accurately directed.
