Abstract

A compact and simple coplanar waveguide fed (CPW-fed) monopole antenna with dual-band applications is proposed. The main features of the proposed antenna are the compact dimensions and band-operating characteristics that are obtained without modifying the radiator or the ground plane. The antenna consists of a square patch as radiator, a partial CPW-ground plane, and a slotted conductor-backed plane. Impedance matching for dual-band operations is achieved by a pair of mirror square-shaped slots at the conductor-backed plane. The proposed antenna has a small size of 15 × 15 × 0.8 mm3, and measured to cover the bandwidth for 5.2 GHz (5150–5350 MHz) and 5.8 GHz (5725–5825 MHz) bands for IEEE 802.11a and also X-band (8–12 GHz) and provides suitable radiation pattern and antenna gains for the operating bands. © 2012 Wiley Periodicals, Inc.
