Abstract

This paper presents a dual-frequency low profile horizontally polarized omnidirectional antenna for WLAN application. The purposed antenna produces horizontally polarized electromagnetic wave at two different frequency caused by multiloop resonance on its wing structures. To prove the validation of the purposed antenna, the measured return losses are 22dB and 35dB at 2.45GHz and 5.5GHz, respectively. The measured VSWRs at these two frequencies are less than 2 and the ovality of omnidirectional radiation patterns is less than 1.8dB. The purposed antenna is achieved for WLAN applications and dual-band MIMO systems.
