Dual-polarized antenna applicable to wireless local area network and manufacturing method of dual-polarized antenna

Abstract

The invention provides a dual-polarized antenna applicable to a wireless local area network and a manufacturing method of the dual-polarized antenna. The antenna comprises two dielectric plates and a grounding plate, which are the same square and overlapped and fixedly connected with one another in the same manner; the upper surface of the first dielectric plate is a metal radiation patch located at the center; two micro-strip feeder lines, which are vertical with each other and are respectively located on the two adjacent edges of a square, are arranged between the two dielectric plates; symmetrical convex rectangles are formed on the four edges of the metal radiation patch; and four cross-shaped grooves in center symmetry are arranged on the grounding plate. The manufacturing method of the antenna comprises the following steps of: respectively manufacturing single-faced and double-faced copper-coated plates to be square plates which are taken as the first and second dielectric plates; etching the first dielectric plate to obtain the metal radiation patch; etching the second dielectric plate to obtain the two micro-strip feeder lines, wherein the bottom face of the second dielectric plate is taken as the grounding plate; machining the four cross-shaped grooves in center symmetry on the bottom face of the grounding plate; connecting the dielectric plates in a laminated manner; and mounting a feeder interface. The dual-polarized antenna provided by the invention is simple in structure and small in thickness, is obviously minimized while property indexes are improved and is strong in maneuverability, and antenna parameters are convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-polarized antenna suitable for a wireless local area network (WLAN for short), and a manufacturing method thereof. Background technique [0002] Wireless local area network (Wireless Local Area Network referred to as WLAN) refers to the application of wireless communication technology to interconnect computer equipment, and the client server can access the Internet and enterprise network at any time through terminals such as notebook computers and PDAs; it is based on IEEE802 .11g standard, which uses radio waves as the medium of data transmission, and the transmission distance is generally tens of meters; the backbone network of the wireless local area network is usually connected by cables, and the user computers of the wireless local area network pass through one or more wireless access points (Access Points, referred to as AP) to access the wireless LAN. Obviously, t...
