Abstract

This paper presents a novel, close-packed coplanar waveguide fed Frequency Reconfigurable antenna. The substrate used in the proposed design is Rogers RT/Duroid 5880 with dimensions 15 mm x 8 mm. This has a thickness of 0.508 mm. The dependent variable, resonant frequency, is a function of current distribution which can be organized by integrating two switches on the surface of the antenna. All possible switch positions result in different current distributions which in turn change the resonant frequencies. The antenna design is simulated on Computer Simulation Technology Microwave Studio software (CST MWS). Over desired frequency bands, the presented antenna reveals an exceptional radiation patterns with positive gain. Good agreement between the theoretical and practical results exists with this design. With the proposed portable design, devices can be used for the Aeronautical Radio Navigation (4.3 Ghz), AMT fixed services (4.5 GHz), WLAN (5.2 GHz) Unlicensed WiMAX (5.8 GHz) and C-band Applications.
