Leaky wave antenna for millimeter wave utilization

Abstract

The simulation of planar periodic leaky-wave antenna for ultra-wideband application is introduced here. The antenna proposed here comprises 15 matched unit cells with high directivity which provides a backward to forward beam scanning range of 80° with frequency from 24.4GHz to 27.5GHz and has filtering capability making the design simpler. The calculated efficiency is 90% which is the gain to the directivity ratio of the designed antenna. The bandwidth range is between 24.4 GHz to 27.5GHz. The work is outlined and assembled on Roger’s substrate (particularly good for 5G applications) and has a gain of 13.92dB which represents an excellent choice for communication systems.
