Abstract

ABSTRACT The modern microwave communication system demands good antenna performance with variety of application. One antenna should serve the purpose of many antennas to reduce the resource cost and installation cost. For this reason the concept of multiband antenna arises. In this paper the attention has been given towards the design of a dual band antenna. In this paper a modified E-shaped compact size probe-feed microstrip antenna is proposed for dual band operation in C-band and X-band with increased bandwidth. The return loss, VSWR and gain is also improved in this antenna design compare to previous work on dual band design. HFSS 13.0 is used for simulation and analysis purpose. Though the proposed design is about dual band operation but the simulated result shows two resonant frequencies of 4.8 GHz and 6 GHz in C-band and 9.2 GHz in X-band which is an another advantage compare to previous work. The performance of this multilayer E-shape antenna is depends on the E-shape of the conducting patch, location and dimension of the layers and location and dimension of the probe feed. The operating frequency of the antenna is 4 GHz. An increased gain of 7 dB is achieved in this antenna.
