Description

technical field [0001] The invention relates to an antenna, in particular to a miniaturized dual-polarized antenna suitable for WLAN and a manufacturing method thereof. Background technique [0002] WLAN (Wireless Local Area Network, Wireless Local Area Network) refers to the application of wireless communication technology to interconnect computer equipment. Customer service can access the Internet and enterprise networks at any time through notebook computers, PDAs and other terminals; it is based on the IEEE802.11g standard , it 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 are connected through one or more APs (Access Points, wireless access nodes) WLAN. Obviously, the antenna is one of the key components for transmitting radio waves in a wireless local area net...

AI Technical Summary

Problems solved by technology

However, due to the inherent narrow bandwidth and low gain of the microstrip patch antenna itself, it is quite complicated to design a dual-polarized antenna.

Especially in practical engineering, the use of antennas often puts forward high requirements on the polarization characteristics of the antenna, and issues such as antenna gain, impedance matching, size and polarization coupling need to be considered, which makes it subject to some restrictions in practical applications. , and become the main technical obstacle in the current microstrip antenna research
