Design and simulation of a high gain antenna for millimeter-wave applications

Abstract

As electronic devices continue to shrink in size, the antenna designers are pushed to reduce the antenna size. This has led to the invention of Microstrip antennas that are found to be compatible with today’s manufactured devices and developed systems due to their low cost, low weight, and small size. With the desire to increase data rates and bandwidth by network service providers to meet the demands of their customers, mm-wave frequency bands have been explored and found to be a solution to overcome the bandwidth problem. Different antenna designs have been proposed by many researchers with the aim of increasing the gain and bandwidth of the antennas. Some of these techniques include: the use of antenna arrays, multiple layersubstrate technique, parasitic patch, defective ground structure, and air gap method among others. The main aim of this project is to design and simulate a high gain microstrip antenna through the use of an air gap method that is suitable for mm-wave applications while assessing the desired parameters like VSWR, bandwidth, radiation pattern, directivity, return loss, and antenna efficiency among others.
