Abstract

The invention discloses a broadband base station oscillator antenna and a base station antenna, the broadband base station oscillator antenna comprises a bottom plate, a substrate and two pairs of support plate groups arranged at an included angle, each support plate group comprises two vertical support plates arranged at an interval, the substrate is located above the bottom plate, and the vertical support plates are connected with the bottom plate and the substrate; two pairs of antenna units forming an included angle of 90 degrees are arranged on the top surface of the substrate, each pairof antenna units comprises two antenna subunits, each antenna subunit comprises an outer ring and an inner ring, and the inner ring is positioned in the outer ring and is connected with the outer ring; each support plate group is provided with an inverted-hook-shaped microstrip line feed balun, and the microstrip line feed balun is coupled with the corresponding antenna unit for feeding. The broadband base station oscillator antenna and the base station antenna are wide in coverage frequency band and excellent in performance, have the advantages of planarization, multimode resonance, stable gain and the like, and are simple in structure, convenient to manufacture and low in production cost.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband base station dipole antenna and a base station antenna. Background technique [0002] With the rapid development of mobile communication, the role of base station antennas in communication networks is becoming more and more important. In order to reduce the processing cost and reduce the base station antenna volume and other factors, the simplification of the antenna structure has gradually become a research hotspot in the design of the base station antenna. At the same time, in order to simultaneously meet the communication system requirements of 2G, 3G, 4G, and China Mobile's 5G in the 2515-2675MHz frequency band, China's base station oscillator antenna needs to cover the 1710-2690MHz frequency band (the working bandwidth is 0.98GHz, or 45.5%). Therefore, how to design a broadband dipole antenna that is easy to process and has a simple structure is a challenge to ...
