Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to an electronic device.
Background
With the advancement of wireless communication technology, people can realize normal conversation in areas with weak signals, such as mountainous areas. However, in the scenes of an underground garage, an elevator, a high-speed rail, a tunnel and the like with weak signals or a communication terminal in a high-speed moving state, the situations of poor communication quality, low call-through rate and even no connection exist. The reason for this is that, on one hand, the signal coverage of the base station is insufficient, and on the other hand, the terminal cannot establish a connection with the base station due to the limited transmission power of the terminal, resulting in poor communication quality or even no connection.
The antenna is a device which converts energy output by a radio frequency circuit into electromagnetic waves in space so as to realize long-distance communication. The antenna efficiency is the ratio of the energy radiated into space to the energy fed into the antenna input port. Higher antenna efficiency represents greater energy conversion capability. The antenna efficiency in the current wireless communication terminal is generally only 20% -40%, and some are even only 10%. The vast majority of energy can not be utilized due to low antenna efficiency, and the high antenna efficiency is beneficial to prolonging the battery endurance time.
At present, three ways for improving the performance of the terminal antenna are available, and the first way is to optimize the antenna layout, improve the isolation of multiple antennas and improve the throughput rate of the system. The above approach can improve the communication quality to some extent, but the implementation of the specific technology is complicated, and the efficiency of a single antenna is not substantially improved. The second method is a beamforming (beamforming) technique for MIMO (Multi-Input-Multi-Output) antennas. The beam forming realizes the beam synthesis in different directions by adjusting the phases of multiple antennas, thereby realizing the improvement of the antenna performance in a certain direction. The method is suitable for directional antennas in millimeter wave frequency bands, and for the frequency bands below 6GHz, the antenna directional diagram has no strong directivity, so that the effect of the beam forming algorithm is not obvious. The third method is to add a clip antenna on the basis of the existing antenna. The method not only increases the cost of the whole machine, but also needs to add an additional antenna supporting structure, and particularly influences the appearance of the product. How to greatly improve the performance of the antenna without changing the structure of the whole antenna becomes a problem to be solved urgently.

Wherein, a containing groove 101 is formed in the hollow interior of the shell 100; the wireless transceiver 3 is accommodated in the accommodating groove 101; the first antenna 1 is accommodated in the accommodating groove 101 and is electrically connected with the wireless transceiver 3; the second antenna 2 is connected with the shell 100 and is opposite to the first antenna 1 in a spaced mode; the second antenna 2 can be selectively electrically connected to the wireless transceiver 3, and the second antenna 2 can be coupled to the first antenna 1 for feeding when the connection is broken.
Specifically, the housing 100 serves primarily as a carrier for carrying internal components of the electronic device. The housing 100 has a rectangular outline, and includes a rectangular rear cover 10 and a side edge 13 extending from the periphery of the rear cover 10 to the same side in a bending manner, and four corners of the side edge 13 are all designed to be rounded corners through circular arc transition. The rear cover 10 and the side edge 13 together enclose a receiving groove 101. The accommodating groove 101 can accommodate electronic components such as a PCB circuit board, a liquid crystal display, the wireless transceiver 3, an antenna, and the like.
As shown in fig. 1, the first antenna 1 is attached to the inner surface of the side edge 13. The first antenna 1 is located on the top of the housing 100, with reference to the view direction of fig. 1.
Referring to fig. 2, the second antenna 2 is disposed on the outer surface of the top of the side edge 13, that is, the first antenna 1 and the second antenna 2 are spaced and opposite to each other with respect to the housing 100.
The second antenna 2 is bendable and has a curvature matched with the outer contour of the side edge 13 so as to be attached and fixed to the side edge 13.
Specifically, the second antenna 2 includes a straight section 21 extending horizontally and two arc sections 23 formed by arc transition from both ends of the straight section 21. The straight edge section 21 is attached to the tip end surface of the side edge 13. In addition, the straight section 21 is provided with a through hole 201 corresponding to the earphone hole arranged at the top of the casing 100, and the straight section 21 is provided with a groove matched with the strip-shaped groove on the casing 100.

The first impedance tuning unit 11 is disposed between the first antenna 1 and the wireless transceiver 3 for reducing reflection of high frequency energy. Similarly, the second impedance tuning section 22 is provided between the second antenna 2 and the antenna switch 4.

When the antenna switch 4 is off, the second antenna 2 is not energized, and it functions as an auxiliary antenna; the second antenna 2 is coupled fed by the first antenna 1 for enhancing the performance of the first antenna 1. When the antenna switch 4 is turned on, the second antenna 2 is energized to operate as an independent antenna, and the second impedance tuning section 22 is used for impedance matching of the second antenna 2.

In this embodiment, the first antenna 1 and the second antenna 2 have a multiband operating characteristic, and can operate in a cellular communication frequency band, and also can operate in a WiFi frequency band, a GPS frequency band, and a beidou frequency band. Specifically, the first antenna 1 operates in a frequency band of a cellular communication network of 700MHz to 5GHz, the impedance matching of the first antenna 1 is changed after the second antenna 2 is integrated with the first antenna 1, and the impedance matching can be performed by the first impedance tuning part 11, so that maximum energy transmission is realized.
