Abstract

The invention discloses a broadband high-isolation dual polarization antenna and a radiating unit of the broadband high-isolation dual polarization antenna. The radiating unit comprises a reflecting plate, a first feed part, a second feed part, a first radiating body, a second radiating body and four supporting parts. The first radiating body and the second radiating body are composed of diagonal radiating bodies. The four radiating bodies are respectively fixed on the four supporting parts which are fixed on the reflecting plate. Tops of the first feed part and the second feet part are crossed in an orthogonality mode and a height difference exists. The first feed part is a feed structure of the first radiating body and the second feed part is a feed structure of the second radiating body. A cross-shaped seam is formed among the four radiating bodies. A rectangle-shaped branch knot which is longer than the radiating body and faces the rim direction of an outer side of the radiating body is arranged in the middle of each radiating body face. A branch knot is arranged at the rim of the outer side of each radiating body. The dual polarization antenna radiating unit and an antenna array composed of the dual polarization antenna radiating unit have the advantages of being high in isolation , high in radiation characteristic, wide in frequency band and the like.

Description

technical field [0001] The invention relates to a dual-polarization antenna, in particular to a wide-band high-isolation dual-polarization antenna and a radiation unit thereof. Background technique [0002] In recent years, with the rapid development of mobile communication, the communication system will inevitably develop from 2G and 3G communication systems to 4G communication systems. Due to the importance of broadband base station antennas in communication systems, the design of broadband base station antennas that meet LTE communication systems become a recent research hotspot. At present, the research on broadband base station antennas at home and abroad mainly focuses on the performance, cost, and assembly of base station antennas. [0003] In order to improve the capacity of the communication system, the polarization diversity technology is generally adopted, and the working efficiency of the antenna is improved by designing a wide-band dual-polarization antenna. O...
