Abstract
ABSTRACTIn this article, a novel coplanar waveguide (CPW)‐fed monopole antenna with three branch strips for wireless local area network (WLAN)/worldwide interoperability of microwave access (WiMAX) triple‐band applications is proposed. The proposed antenna is simply composed of three branch strips. By carefully selecting the positions and lengths of these branch strips, the desired resonant modes excited at 2.46/3.6/5.4 GHz with less than −10 dB frequency responses to the impedance can be achieved. In addition, an acceptable agreement is obtained between the simulation and the experiment. Also, the compact design of the proposed antenna, which has enough impedance bandwidth, makes the antenna suitable for WLAN and WiMAX operations. This article further presents and discusses the 2D radiation patterns and 2D gains according to the experiment results. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:161–166, 2015
