Abstract

A double-frequency dual-polarized antenna array belongs to the field of antennas for wireless communication, and solves problems of long feed line lengths and big antenna sizes in existing antenna arrays. The double-frequency dual-polarized antenna array is applicable to networks such as wireless local area networks and WiMax networks. The double-frequency dual-polarized antenna array comprises a horizontal substrate, N horizontally-polarized antennas and N vertical polarized antennas. The N horizontally-polarized antennas which are distributed in a symmetrical and uniform mode around the center of the circle of the horizontal substrate are printed on the horizontal substrate. The horizontally-polarized antennas are completely identical to each other in terms of shape and size. The N vertical polarized antennas are printed on rectangular substrates, and are respectively inserted into N grooves at the circumference of the horizontal substrate, so that each rectangular substrate is perpendicular to the horizontal substrate. A double-frequency dual-polarized structure is employed by the invention, so that the size of the antenna is shortened, and a Mimo technique and an intelligent antenna wave beam switching technique in wireless communication are effectively supported. One typical application is to support wave beam switching technique and a MIMO technique of a 2.4 GHz / 5 GHz wireless local area network, and a system capacity and an anti-interference performance of the wireless local area network can be substantial raised.

Description

technical field [0001] The invention belongs to the field of wireless communication antennas, in particular to a dual-frequency dual-polarization antenna array, which is suitable for networks such as wireless local area networks and WiMax. Background technique [0002] With the large-scale popularization and application of wireless communication, the requirements for the wireless communication system are higher, not only needing it to have a high rate, but also requiring it to be able to effectively resist interference. Smart antenna technology and Multiple Input Multiple Output (MIMO) technology are two technologies widely used in wireless communication systems. The smart antenna technology improves the anti-interference performance of the system by directing the beam synthesized by the smart antenna array to the user signal and aligning the null trap with the interference signal; MIMO technology makes full use of the multipath characteristics of the wireless channel, The ...
