Abstract

The invention discloses a patch antenna with broadband and filtering characteristics. The patch antenna comprises a metal bottom plate, a dielectric substrate attached to the metal bottom plate, a first resonance unit arranged on the surface of the dielectric substrate and a second resonance unit coupled with the first resonance unit, a radiation patch located above the dielectric substrate, a feed component inner conductor connected with the first resonance unit and penetrating through the dielectric substrate and the metal bottom plate, and a feed component outer conductor disposed on the surface of the metal bottom plate and in communication with the feed component inner conductor. The patch antenna with the broadband and filtering characteristics provided by the invention overcomes theshortcomings and realities of the narrow bandwidth, low gain and poor filtering characteristics of an existing patch antenna, and satisfies the requirements of the antenna wide frequency band, high gain and excellent filtering characteristic in a wireless communication system.

Description

【Technical field】 [0001] The invention belongs to the technical field of communication, in particular to a patch antenna with broadband and filter characteristics. 【Background technique】 [0002] Patch antennas are widely used in wireless communication systems due to their advantages of low profile, small size, and easy conformality. The traditional patch antenna consists of a metal patch with a specific shape and a metal ground plate, and a dielectric is filled between the two to separate them. The coaxial probe feeding method is usually used to feed the patch. [0003] At present, high speed, large capacity and high integration are the development trends of mobile communication systems. Therefore, the operating bandwidth, gain and low profile of the antenna are regarded as important technical indicators. However, the traditional patch antenna has a relatively narrow bandwidth. In order to improve the working bandwidth of the patch antenna, it is usually realized by impro...
