Abstract

The embodiment of the invention discloses a wideband dual-polarization array antenna and a base station, wherein the wideband dual-polarization array antenna includes an antenna unit, a metal reflection board, and a metal separation board, the antenna unit being separated by the metal separation board. The antenna unit contains a feed piece and a double-layer radiation patch. A first end of the feed piece is configured at the bottom radiation patch of the double-layer radiation patch so as to form a feeding point, and a second end of the feed piece is connected to a feed structure so as to form a feeding port. The bottom patch of the double-layer radiation patch is provided a slot at the upper surface thereof. A hole is opened within the slot to fixedly connect the fist end of the feed piece in order to form capative reactance. The embodiment of the invention form capative reactance by providing a slot on the upper surface of the bottom patch of the double-layer radiation patch of the array antenna, which enables an easy resonance in each radiation patch of the double-layer radiation patch of the array antenna. The array antenna can realize wideband with efficiency.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular to a broadband dual-polarization array antenna and a base station. Background technique [0002] With the rapid development of wireless communication technology, the bandwidth and performance requirements of antennas are getting higher and higher. Whether it is a military communication or a civilian communication system, there is a demand for high-performance base station antennas. [0003] The size and bandwidth of the antenna in the prior art are the main obstacles restricting the miniaturization of the communication system. A reduction in the size of the antenna means a reduction in other performances of the antenna, such as bandwidth and efficiency. Therefore, the miniaturization design of the communication system needs to find a compromise in the performance parameters of the antenna, such as directivity coefficient, gain, radiation efficiency, ...
