Micro-strip array antenna and base station

Abstract

The invention discloses a micro-strip array antenna and a base station, and relates to the technical field of antennas. The micro-strip array antenna and the base station aim to resolve the problems that when a probe is installed and welded manually, production efficiency is low, welding consistency is poor, and a certain degree of deterioration of electrical performance of the antenna will be caused. The micro-strip array antenna comprises a plurality of conductor layers and insulation interval layers, one insulation interval layer is arranged between every two conductor layers, the conductor layers and the insulation interval layers are arranged in a stacked mode, and at least one of the conductor layers is a reference ground layer; at least one conductor layer is a radiation unit layer; at least one conductor layer is a feed network layer; all feed points on the at least one radiation unit layer are correspondingly connected with all feed points on the at least one feed network layer through metallization via holes in the insulation interval layers. The micro-strip array antenna and the base station can be used for design of mobile communication base antennas.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a microstrip array antenna and a base station. Background technique [0002] Microstrip antennas include many structural forms. From the perspective of the composition of microstrip antennas, microstrip antennas include three basic components, namely the radiation unit, the reference ground, and the feed structure. [0003] Since the array antenna has multiple radiating elements, the feed structure needs to use a feed network to distribute the power of the input signal according to a certain power ratio and phase relationship. [0004] figure 1 and figure 2 Shown are two layout forms usually adopted by the feeding network of the microstrip array antenna in the prior art: [0005] refer to figure 1 , figure 1 The shown array antenna structure includes two radiating units 1 and one signal input port 3 , after the signal is input, it is respectively connected to the two radia...

Problems solved by technology

[0009] Embodiments of the present invention provide a microstrip array antenna and a base station, so that the array antenna does not need to use probes when the rear feed structure is used, thereby overcoming the low production efficiency and consistent welding when manually installing and welding probes in the prior art Poor performance will lead to a certain degree of deterioration in the electrical performance of the antenna
