| dc.description.abstract | Purpose that thesis study this is it discuss which kind of antenna is it apply to 802.11n WLAN AP most to make up to lie in, and design the antenna in analysis according to this. Introduction of WLAN, is it analyses why it will be antenna demand of system this to go on then from the beginning, and then design, improve from various kinds of parameter characteristics of the antenna, and then after the verification of the electromagnetic simulation software, entering and proving and testing in fact, get an intact antenna of associations finally, its characteristics of various fields all accord with this thesis to plan and set up, and compared with known antenna, there is progress by a wide margin, among them the efficiency of the antenna has been improved by more than 35%, the average gain of azimuth plane has improved and exceeded 4dB by a wide margin even more, the average gain of azimuth plane is higher than 0dBi, at the same time this antenna was made up great diversity also on the space, polarization and radiation patterns, really become suitable for 802.11n WLAN AP. | en_US |
