Multiband MIMO Antenna System with Parasitic Elements for WLAN and WiMAX Application

[摘要] A new microstrip slot antenna with parasitic elements has been presented in this paper. The proposed antenna is composed of a microstrip feed line, a ground plane on which some simple slots are etched, and parasitic elements. Simulation results show that the antenna structure allows for the independent adjustment of each frequency. A two-element array configuration of this antenna for MIMO application is investigated as well. For comparison between simulation and measurement result both single and array configurations have been fabricated. The measurement result exhibits good radiation performance in terms of return loss, low mutual coupling, and compactness.
