Problems solved by technology

[0002] The current 5G antenna uses a phased array to realize beam scanning. The beams are scanned according to certain rules and cannot be automatically adjusted according to environmental changes.
However, the traditional adaptive antenna array algorithm is complex and needs to integrate splitters and direction shifters to achieve beamforming. Currently, the cost of power splitters and direction shifters for terminals is too high

Embodiment Construction

[0030] At present, the antennas of 2G, 3G, and 4G mobile terminals are generally omnidirectional antennas, which do not have the ability to resist signal interference. With the development of 5G, antennas applied to 5G mobile terminals have become a concern. In the existing technology, the 5G antenna uses a phased array to realize beam scanning, which cannot be automatically adjusted according to changes in signal strength. However, the traditional antenna array algorithm is complex and not suitable for 5G mobile terminals.

[0031] An embodiment of the present application provides an antenna group, which is applied to a 5G mobile terminal. The antenna group includes at least two Yagi antenna units for receiving signals, and radio frequency switches corresponding to the Yagi antenna units one by one. The other end is connected to the comparator signal through the radio frequency transceiver link. The comparator is also signally connected to the control unit, and the compara...

Abstract

The embodiment of the invention provides an antenna group, relates to the field of electronic communication equipment terminals, and is used for realizing automatic adjustment of antennas according toenvironmental changes. The antenna group comprises at least two yagi antenna units, radio frequency switches in one-to-one correspondence with the yagi antenna units, a radio frequency transceiving link, a control unit and a comparator. The yagi antenna units are used for receiving signals. In each pair of corresponding yagi antenna units and radio frequency switches, one end of one radio frequency switch is connected with the corresponding yagi antenna unit, and the other end of the radio frequency switch is in signal connection with the corresponding comparator through the radio frequency transceiving link. The comparator is in signal connection with the control unit and is used for comparing the signal intensities received by the at least two yagi antenna units and sending a comparisonresult to the control unit. The control unit is used for controlling the radio frequency switches connected with a yagi antenna unit with the maximum signal intensity in the comparison result to be closed. Thus, the antenna unit with the maximum signal intensity can be selected for the terminal to receive and transmit data, and the data receiving and transmitting efficiency can be improved.

Description

technical field [0001] The present application relates to the field of electronic communication equipment terminals, and in particular to an antenna group. Background technique [0002] The current 5G antenna uses a phased array to realize beam scanning. The beams are scanned according to certain rules and cannot be automatically adjusted according to environmental changes. However, the algorithm of the traditional adaptive antenna array is complicated, and it needs to integrate a splitter and a direction shifter to realize beamforming. Currently, the cost of the power splitter and the direction shifter used in the terminal is too high. Contents of the invention [0003] In order to realize that the antenna of a 5G mobile terminal can be automatically adjusted according to an environment change, an embodiment of the present application provides an antenna group. [0004] The antenna group is applied to a 5G mobile terminal, and the antenna group includes at least two Yagi...
