Wide to multiband reconfigurable antenna

Abstract

A wideband antenna fed by a coplanar waveguide (CPW) with reconfigurable function is presented. The wideband function is achieved from 1.39 GHz to 8.11 GHz using an elliptical radiator with a CPW feed line. Meanwhile, three pairs of slot dipoles which are fed by CPW are used to achieve triple‐band function at 2.4 GHz, 3.5 GHz and 5.2 GHz. Four ideal switches are placed on the proposed antenna. The proposed antenna is designed, simulated, fabricated and tested. All simulated and measured results of return loss, radiation pattern and gain are presented. Good results of return loss and radiation pattern are obtained thus verifying that the proposed antenna is suitable for future multimode radio systems. © 2016 Wiley Periodicals, Inc.

Folded monopole antenna with CSRRS for tri-band applications

“…Although, a miniaturized multiband antenna has been designed by cutting slot, which is suitable for WLAN application [2]. Similarly, a multiband reconfigurable antenna [3] has been designed by embedding three pairs of slot dipoles for achieving three bands of operation (2.4/3.5/5.2GHz). However, as we know there are various techniques by which we can reduce the size of the antenna such as cutting slots, using meandered line and using fractal [1][2][3][4][5].…”
