Abstract

This study proposes a novel design of printed monopole antenna using branch slits for WiMAX applications. Here, dual‐band‐reject function is used to form triple band for WiMAX operation. We first investigated the printed rectangular monopole antenna for wide‐band operation of 2.5–6 GHz, and the meandered slit strip etched on the wide‐band printed rectangular monopole antenna with a rejected frequency of 2.9–3.1 GHz. Furthermore, we embedded two short slits etched on the signal strip of the 50‐Ω CPW‐fed line, which is approximately quarter wavelength to suppress the band of 3.96–4.9 GHz. This study demonstrates good impedance matching, good radiation patterns, and good band‐rejected performance of the proposed antenna. © 2008 Wiley Periodicals, Inc.

## Abstract A novel G‐shaped antenna with a coplanar waveguide (CPW) feed is proposed. The advantages of a CPW feed are to simplify the antenna structure with a single metallic level and reduce the antenna size. Operating resonant modes of the proposed antenna are related to the length of two folde
