Abstract

The invention discloses a dual polarization base station antenna with Y-shaped feed units. The dual polarization base station antenna with the Y-shaped feed units comprises a dielectric substrate, a metallic reflection plate, a first coaxial line and a second coaxial line. The two sides of the metallic reflection plate are provided with metal flanges. The lower surface of the dielectric substrate is provided with a first annular radiating element, a second annular radiating element, a third annular radiating element and a fourth annular radiating element, wherein the first annular radiating element and the second annular radiating element are in mutual symmetry to form a first antenna structure, and the third annular radiating element and the fourth annular radiating element are in mutual symmetry to form a second antenna structure. The upper surface of the dielectric substrate is provided with the first Y-shaped feed unit and the second Y-shaped feed unit. The first coaxial line is connected with the second annular radiating element and the first Y-shaped feed unit. The second coaxial line is connected with the fourth annular radiating element and the second Y-shaped feed unit. The dual polarization base station antenna is good in performance, simple in structure, easy to process, low in processing cost and convenient to adjust.

Description

technical field [0001] The invention relates to a base station antenna, in particular to a dual-polarization base station antenna with a Y-shaped feed unit, belonging to the technical field of mobile communication antennas. Background technique [0002] In the cellular mobile communication system, the base station antenna is the converter of the electrical signal of the communication equipment and the space radiated electromagnetic wave. It plays a pivotal role in the entire communication system, and its performance will directly affect the overall performance of the entire system. Through the intermediary function of the base station antenna, the coverage of the mobile communication network is wider, the communication capacity is larger, the rate is higher, and the service items are more abundant, and the existence of the base station antenna reduces the radiation power of the mobile station antenna, effectively protecting the The human body is protected from strong electro...
