Problems solved by technology

However, the height of the existing dipole is generally 1 / 4 wavelength of the center frequency point, and the profile is relatively high, so it is not easy to miniaturize. The radiating element is required to have sufficient size in the width direction, and the performance will be further deteriorated in the case of limited width and height

Abstract

The invention discloses a broadband dipole. The broadband dipole comprises a reflection plate and a radiation unit installed on one side surface of the reflection plate. The radiation unit comprises aradiation assembly, a feed balun and a matching network. The radiation assembly is electrically connected with the matching network through the feed balun, the matching network is fixed on the reflection plate, and the radiation assembly is integrally of a curved surface structure arched towards the direction far away from the reflection plate. The radiation assembly comprises a flexible radiation base body and an insulating supporting piece, wherein the radiation base body is attached and fixed on the insulating supporting piece, and the insulating supporting piece is fixedly connected withthe reflecting plate. According to the invention, the effect of realizing broadband performance in an extremely small space can be achieved.

Description

technical field [0001] The invention relates to the field of mobile communication and is applied to an antenna network system, in particular to a broadband dipole used as a base station antenna. Background technique [0002] With the rapid development of the communication industry, the requirements for antenna performance are getting higher and higher. The antenna is required to have good matching and pattern characteristics in a limited space and a wide frequency band. So the current research focus is on broadband, miniaturization and so on. [0003] Among them, the dipole antenna has a series of advantages such as simple structure, stable performance, wide operating frequency range, and easy mass production, and has been widely used in antenna systems. However, the height of existing dipoles is generally 1 / 4 wavelength of the center frequency point, and the profile is relatively high, so it is not easy to miniaturize. The radiating element is required to have a sufficie...
