CPW Fed Tapered Slot Antenna at 5.5 GHz for Wireless Applications

In this paper is to give a novel approach in the design and development of Coplanar Waveguide fed tapered slot antenna for various 5 to 6 GHZ frequency band applications. The fundamental parameters of the antenna such as bandwidth, return loss, gain, radiation pattern and polarization are obtained. All meets the acceptable antenna standards. The measured input impedance bandwidth (return loss >10 dB) of the prototype antenna is 21% (4.8 - 6 GHz). The radiation patterns are bidirectional in the E-plane and H-plane. The simulated peak antenna gain is 3.1 dBi. Procedure to improve the peak gain is also presented. Simulation tool, based on the method of moments (ZELAND IE3D version 12.0) has been used to analyze and optimize the antenna.
