Description
Technical Field
The present invention relates to computer technologies, and in particular, to an information processing method and an electronic device.
Background
Currently, antennas of electronic devices such as smart phones and tablet computers generally employ a conventional monopole (monopole) Antenna or an Inverted-F Antenna (IFA). However, when the electronic device has an all-metal housing or an all-metal bezel, the headroom required for the conventional monopole antenna or IFA antenna is lost, resulting in the conventional monopole antenna or IFA antenna not being operable.
Typically, for electronic devices having an all-metal housing or all-metal bezel, a conventional Planar Inverted-F Antenna (PIFA) is employed in conjunction with a switch (switch). Since the PIFA antenna is a resonant antenna, the Q value of the antenna is high, which results in a narrow radiation bandwidth of the antenna, and therefore even if a switch, such as a single pole Double Throw (SP 2T) switch or a SP4T switch, is used to switch to another frequency band, the efficiency of the antenna is low, and the requirement of efficiency in a high frequency bandwidth cannot be met.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In the present application, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict. The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
In a first embodiment of an electronic device provided by the present invention, as shown in fig. 1, the electronic device includes a communication module, the communication module includes a signal transceiving unit, a PIFA antenna and a first antenna switch, and the PIFA antenna is electrically connected to the first antenna switch; the communication module further comprises a loop antenna and a second antenna switch, the loop antenna is electrically connected with the second antenna switch, and the signal receiving and transmitting unit is used for signal transmission between a main board of the electronic device and the PIFA antenna and the loop antenna; wherein,
the PIFA antenna and the first antenna switch form a first communication channel, the first communication channel works in a low-frequency band, the loop antenna and the second antenna switch form a second communication channel, and the second communication channel works in a high-frequency band. Referring to fig. 2, the loop antenna includes a feeding terminal 21, a grounding terminal 22, and an antenna main body 23.
Here, the loop antenna may be a single loop or multi loop antenna.
In practical applications, the first antenna switch may adopt an SP2T switch or an SP4T switch, and the second antenna switch may adopt an SP2T switch or an SP4T switch.
It is understood that the feeding terminal of the PIFA antenna is connected to the first antenna switch, and the first antenna switch is located between the feeding terminal of the PIFA antenna and the signal transceiving unit. Referring to fig. 3, the PIFA antenna includes a feeding terminal 31 and a grounding terminal 32.
It should be noted here that an important difference of the Loop antenna with respect to the conventional PIFA antenna is that the default resonance is one half wavelength, which is slightly larger than one quarter wavelength of the conventional PIFA, and even then, the antenna area required by the single high frequency is still small, which can be satisfied by the mainstream large screen mobile phone.
In this embodiment, the low-frequency part adopts a conventional PIFA antenna design, and an SP2T or SP4T switch (specifically according to the frequency band requirement) may be added to the feeding end, so that two or four frequency bands may be cut. According to the frequency band requirement of the existing LTE, the maximum required bandwidth of the low-frequency part needs 698-960MHz and is about 260MHz, so the radiation bandwidth of the conventional PIFA antenna can basically meet the bandwidth requirement, once the standing wave bandwidth is successfully switched by the antenna switch, the final radiation performance of the antenna is ideal and can meet the requirement.
The high frequency part of the embodiment of the present invention will be described below by taking the SP4T switch as an example of the second antenna switch. Because the loop antenna can simultaneously excite half-wavelength, three-quarter-wavelength or even full-wavelength modes, the loop antenna really used for actual product design can be bent back and forth, because the loop antenna moves back and forth, the current on the antenna pattern (pattern) can be coupled, and the default central frequency of the frequency doubling modes of three-quarter, full-wavelength and the like can be shifted to low frequency. The frequency band requirement of LTE for high frequency is from 1710 and 2690MHz, and the bandwidth is about 1GHz, which requires that the bandwidth of each path of SP4T must reach more than 250MHz to finally cover the bandwidth of 1 GHz. Under the condition that the antenna environment is severe, the default bandwidth of the antenna may not meet the bandwidth requirement of 250MHz, and at the moment, the invention can excite the inherent high-frequency mode of the loop antenna under the condition that the original mode bandwidth does not reach the bandwidth of 250MHz, thereby realizing that one branch of the switch comprises two frequency bands, and finally meeting the bandwidth requirement of 1GHz under the condition of SP 4T.
As can be seen from the above, for an electronic device with an all-metal housing or an all-metal frame, the embodiment of the present invention adds a second communication channel operating in a high frequency band, and since the loop antenna resonates at one-half wavelength by default, and at the same time, can excite a three-quarter wavelength mode, even a full wavelength mode, and after a multi-mode is excited, the radiation bandwidth of the antenna can be expanded to a very wide range, the technical solution of the embodiment of the present invention can improve the efficiency of the antenna, and meet the requirement of efficiency in a high frequency bandwidth.
