Abstract

This paper has considered the development of a low profile unidirectional antenna for WLAN application, performed with frequency range 2.4-2.4835 GHz. The motivation for this work was the need for an effective directional antenna to be used with the access point. The Radial Waveguide Slot Array Antenna (RWSA) is investigated as a low profile, lightly weight, simple but effective, easy to design and fabricate with reasonable cost efficient. The initial element design was first optimized in the structure based on Zeland Fidelity, FDTD (Finite-Difference Time-Domain) with Full-3D EM Simulation for the radiation pattern, and return loss. The second part of this paper deals with producing design relying on optimum simulation results, the antenna tested in terms of return loss, gain and radiation pattern. Finally, experimental trial had been consociate and compared RWSA Antenna with a monopole antenna on an Access point for WLAN by using AirMagnet software. Measurements are conformed to results presented by the prototype simulation.
