Abstract

A novel and compact dual band partial ground coplanar waveguide (CPW) fed monopole modified elliptical antenna design is proposed. Dual band antenna is designed to cover both WLAN band at 2.4 GHz and WiMAX band at 3.5 GHz. Antenna exhibits good return loss characteristics in both the bands. Antenna is designed on RT/Duroid 5880 with dielectric constant 2.2, thickness 1.6 mm and loss tangent 0.0009 to improve the efficiency. Antenna parameters are optimized with respect to dual band characteristics. Based on these optimized parameters antenna prototype is fabricated. Radiation pattern of the proposed antenna is quasi semi-omnidirectional. Parallel agreement between simulated and measured results makes the proposed dual band antenna suitable candidate for modern wireless communication systems.
