Abstract

See full text

Disclosed in the present disclosure are a dual-polarized broadband millimeter-wave filtering antenna based on a meta-surface, and a communication device. The dual-polarized broadband millimeter-wave filtering antenna based on a meta-surface comprises two layers of dielectric substrates, which are arranged in a stacked manner, wherein an upper surface and a lower surface of a lower-layer dielectric substrate are respectively provided with an upper-layer metal ground and a lower-layer metal ground, an upper surface of an upper-layer dielectric substrate is provided with a meta-surface structure, the meta-surface structure comprises N metal patches, which are arranged in an array, a slot is etched on each metal patch, the upper-layer dielectric substrate is connected to the upper-layer metal ground, and a Jerusalem cross slot is etched on the upper-layer metal ground. The antenna has a simple structure, and radiation and filtering can be realized at the same time without increasing the size of the antenna, thereby greatly reducing the volume of a radio-frequency front end and without any extra insertion loss.
