Title: Antenna, and communication device
Inventor: PAN XIN
IPC: H01Q1/22
Filed: 2018-12-05
Abstract: An antenna and a communication device. The antenna comprises a radiation region, a grounding region, and a feed region. At least one of the radiation region, the grounding region, and the feed region is provided with a variable impedance circuit therein. When the impedance of the variable impedance circuit with respect to the antenna does not match the impedance of a radio frequency front end, or the impedance of the radio frequency front end is changed, the variable impedance circuit adaptively adjusts the impedance of the antenna, so as to control the impedance of the antenna to achieve a conjugate match with the impedance of the radio frequency front end. The antenna enables adaptive adjustment of the impedance thereof to achieve conjugate matching and to reduce energy losses in a radio frequency link, thereby ultimately improving the overall radiation efficiency of a communication device. Alternatively, when the impedance of the antenna matches the impedance of the radio frequency front end, the variable impedance circuit adaptively adjusts the impedance of the antenna, so as to control the impedance of the antenna to achieve a mismatch with the impedance of the radio frequency front end. In this way, an energy loss of an interference signal is increased by adjusting a radio frequency link to achieve impedance mismatch, thereby reducing interference on an antenna system.
