Abstract

The invention relates to an antenna radiator structure and a patch antenna thereof. The structure comprises a radiator with a pair of diagonal structures, and the radiator is connected with a feed part. The diagonal structures are respectively provided with a first gap for clutter inhibition, and one side of the radiator is provided with a second gap for clutter inhibition. The other side, opposite to the second gap, of the radiator is connected with the feed part. According to the invention, the antenna is enabled to inhibit clutters in a high-order mode through the first gaps at the opposite corners of a patch and the second gap at the side. The second gap at the side of the patch enables a current path to be prolonged, and the size of the patch is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna radiator structure and a patch antenna thereof. Background technique [0002] Antenna is a component that radiates and receives electromagnetic wave energy in systems such as wireless communication, radio and television, satellite communication, navigation, and cordless telephone. role. With the rapid development of modern wireless communications, especially the wide application of WLAN (Wireless LocalArea Network), LTE (Long Term Evolution, long-term evolution) and CDMA (Code Division Multiple Access, Code Division Multiple Access), people are concerned about the performance of the antenna Increasingly demanding. [0003] Due to the complexity of the wireless propagation environment, the antenna often receives clutter from various scatterers when receiving signals. In order to maintain the demodulation quality of the received signal, the antenna needs to have...
