Abstract

The invention discloses a bipolar antenna with a planar monopole and a slot structure. A monopole radiation oscillator and a metal floor are set on an upper surface and a lower surface of a dielectricsubstrate, thereby jointly forming a planar monopole antenna unit. A slot is set on the metal floor to form a slot antenna unit. A feed structure unit is composed of a metal connection part and two feed ports which penetrate the dielectric substrate. The feed structure unit is used for carrying out electrical connection on the monopole radiation oscillator and the metal floor. Through utilizationof polarization orthogonal characteristics of the two antenna units, two different linearly polarized waves on the same frequency are achieved in different feed modes. The planar monopole antenna unit and the slot antenna unit are characterized by low profiles, light weight and easy processing, so the bipolar antenna formed by the planar monopole antenna unit and the slot antenna unit also has the advantages of a simple structure, a small size, and easy processing and production.

Description

technical field [0001] The invention relates to a dual-polarization antenna, in particular to a dual-polarization antenna with a planar monopole and slot structure. Background technique [0002] The dual-polarized antenna radiates polarized waves in different directions through different feeding methods, which is conducive to achieving effective diversity in transmission, thereby combating the decline in communication quality caused by multipath fading, and can be used in MIMO systems as a Transmitting antenna or receiving antenna. [0003] The relative radiation polarization purity of the existing dual-polarized antenna is not high, and at the same time, the design flexibility is low. Contents of the invention [0004] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a dual-polarized antenna with planar monopole and slot structure. High polarization purity and design flexibility. [0005] Technical solution: A ...
