Abstract

The invention discloses a broadband wide beam dual-polarization dipole antenna, belonging to a dipole antenna. The broadband wide beam dual-polarization dipole antenna comprises an antenna cover plate, a reflection plate and a first antenna dielectric slab and a second antenna dielectric slab in cross fixing, wherein the first antenna dielectric slab and the second antenna dielectric slab are mounted on the reflection plate; the antenna cover plate is supported by at least three support columns and placed above the reflection plate, the first antenna dielectric slab and the second antenna dielectric slab; and toothed rails are arranged at the outer parts of the first antenna dielectric plate and the second antenna dielectric plate and also mounted on the reflection plate. By adding the toothed rails around the dipole antenna dielectric slabs, the antenna operation is effectively expanded, and the width of the wide beam is increased; the antenna unit covers the frequency range of 1,710-2,690MHz when the standing wave is less than 1.4, and is directly fed through a microstrip feeder and a through hole with a metalized edge in the reflection plate; and moreover, the processing is easy, the integration of an antenna and a feed network after array formation is facilitated, and the application range is broad.

Description

technical field [0001] The invention relates to a dipole antenna, and more specifically, the invention mainly relates to a wide bandwidth beam dual-polarization dipole antenna. Background technique [0002] The base station antenna plays a connecting role in the mobile communication system, and is a sensor for transmitting and receiving electromagnetic waves. The performance of the antenna plays a decisive role in the entire communication system. The cost of the antenna accounts for only a few percent of the total cost of the entire base station. However, its excellent performance can affect 30% to 50% of the reliability of the base station system. Therefore, a pair of high-performance antennas can relax system design requirements and improve overall system performance. With the widespread use of 3G in our country, the research on the IMT-Advanced (International Mobile Telecommunication-Advanced) communication system for the next generation of mobile communication has becom...
