A Compact Flexible and Frequency Reconfigurable Antenna for Quintuple Applications

Abstract

A novel, compact coplanar waveguide fed flexible antenna is presented. The proposed design uses flexible Rogers RT/duroid 5880 (0.508mm thickness) as a substrate with small size of 30×28.4 mm^2. Two switches are integrated on the antenna surface to change the current distribution which consequently changes the resonance frequency under different conditions of switches, thereby making it a frequency reconfigurable antenna. The antenna design is simulated on CST®MWS®. The proposed antenna exhibits VSWR<2 and appreciable radiation patterns with positive gain over desired frequency bands. Good agreement exists between simulated and measured results. On the basis of results, the proposed antenna is envisioned to be deployed for the following applications; aeronautical radio navigation [4.3 GHz, AMT fixed services [4.5 GHz, WLAN [5.2 GHz, Unlicensed WiMAX [5.8 GHz and X-band [7.5 GHz.
