A simple wave-traps MIMO antenna design for WLAN application

摘要

A simple wave-traps multi-input multi-output (MIMO) antenna design is presented for wireless local area network (WLAN) operation. The measured -10 dB bandwidths for return loss are covering the WLAN2.4 and Wlan5.2/5.8 bands. The antenna structure is uncomplicated; it's composition by two symmetrically antennas and places on the clear-area which is at upper substrate. The proposed MIMO antenna system also has the good performances on isolation characteristic, which value are all under -15 dB at the required bandwidth.
