MINIATURIZED DUAL-FREQUENCY DUAL-POLARIZED FILTERING ANTENNA HAVING HIGH DEGREE OF ISOLATION

WIPO Patent Application WO/2019/085504

A1

Disclosed is a miniaturized dual-frequency dual-polarized filtering antenna having a high degree of isolation. The antenna comprises a reflecting floor, a filtering patch antenna unit and a bowl-shaped filtering symmetric vibrator antenna unit. The filtering patch antenna unit comprises a first layer of metal sheet and a second layer of metal sheet. The first layer of metal sheet is arranged above the reflecting floor. The bowl-shaped filtering symmetric vibrator antenna unit comprises four symmetric vibrator antenna units; and the four symmetric vibrator antenna units are of the same structure and are respectively located on an edge of the first layer of metal sheet. By means of applying a filtering antenna unit without an additional loss circuit as a basic composition unit of a dual-frequency dual-polarized filtering antenna, the mutual coupling between two frequency band antennas can be reduced using a filtering property thereof, the degree of isolation between two working frequency bands can be improved, and the insertion loss caused by a filter can be eliminated, thus increasing the gain of the antenna.
