Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>In this article, a novel and compact printed half‐ring dipole antenna for WLAN communications is proposed. The proposed dipole antenna consists of a tapered balun and a pair of half‐ring dipole which have both the modified microstrip half‐ring with a feed line and the modified microstrip half‐ring with the tapered balun on the ground plane. The proposed antenna has a decreased physical size and radiates an omnidirectional pattern compared with conventional dipole antenna because of the proposed ring dipole antenna uses a circular‐type dipole. Prototypes of the proposed antenna for the 4.9–6 GHz bands are constructed and tested. The proposed antenna obtains a measured peak gain of about 5.8 dBi at 5.32 GHz, and an appeared circular polarization pattern at 5.04 GHz. © 2014 Wiley Periodicals, Inc.
