Title: Antenna, antenna array, and communication device
Inventor: LUO BING
IPC: H01Q1/38
Filed: 2020-07-06
Abstract: The present application provides an antenna, antenna array, and communication device; the antenna comprises a radiating part and a feeding part, the feeding part being coupled to the radiating part and used for feeding power to the radiating part, causing the radiating part to radiate a low-frequency signal outward; the radiating part comprises one or a plurality of frequency selection units having bandpass characteristics, and the radiating part is a structure which can excite coupling currents that cancel out in pairs when high-frequency signals pass through. When a high-frequency signal passes through the radiating part, each pair of coupling currents excited on the radiating part appears as a pair and the currents can cancel each other out, which can reduce, or even completely eliminate, the high-frequency induced current at the same frequency as the high-frequency signal on the radiating part. Thus when a high-frequency signal passes through, the radiating part can only radiate fewer, or no, electromagnetic waves having the same frequency as the high-frequency signal, which is conducive to improving pattern parameters such as the gain stability and polarization suppression ratio of high-frequency antenna which transmits high-frequency signals.
