摘要

A novel triple-band antenna element by etching parasitic slot on ground plane is presented.rnA three-element antenna system for WLAN MIMO communications isrnfabricated by using the proposed antenna element. The triple-band antenna element isrndesigned for the WLAN standard frequency ranges (2.4-2.485, 5.15-5.35, and 5.475-rn5.725 GHz). The three identical antenna elements are rotationally symmetric on thernsubstrate, isolated by using metal-vias cavity. The measured average peak gain withinrnthe operational bandwidth is about 2.7 dBi. The isolation between the antennarnelements can achieve better than 17 dB at the lower band (2.25-2.65 GHz), whilernmore than 32 dB at the higher bands (5.20-5.35 and 5.47-5.73 GHz) is obtained.
