Cylindrical Omnidirectional Slotted Waveguide Antenna with optimized directional characteristics

Abstract

Antennas, nowadays, are used in many systems especially in wireless internet communications and military Radar applications where high power handling capability, high gain along with reliable mechanical characteristics is needed. However, these parameters are very hard to simultaneously optimize, there is always a trade-off in between. In this paper, a Cylindrical Omnidirectional Slotted Waveguide Antenna (COSWA) is presented. The purpose of this paper is to provide an optimized version of circular slotted waveguide antennas by simply selecting the optimum position, number, shape and size of the slots within the waveguide wall. Such configurations are suitable to be used in Wireless internet distributing systems, Military radar applications and even oil drilling devices. Simulation results along with Experimental validations will be conducted at 2.4 GHz frequency demonstrating high effectiveness in terms of directivity and high gain given a reduced cost, simplicity and size.
