Design and Analysis of High Gain Wideband Antennas Using Square and Circular Array of Square Parasitic Patches

Abstract

This paper deals with design and comparative analysis of square array of square Parasitic Patches (PPs) and circular array of square PPs on superstrate layer fed by Microstrip Antenna (MSA) on the basis of gain, bandwidth, efficiency and number of PPs required to obtain desired performance. The first structure consists of MSA, which feeds square array of 5×5 square PPs printed below a FR4 superstrate and positioned at about 0.5λ0 height from the ground plane. While other structure consists of a MSA, which feeds circular array of 18 square PPs printed below a FR4 superstrate and positioned at about 0.5λ0 height from the ground plane. It is shown that the circular arrangement of square PPs have better performance. The analysis is useful in selecting the antenna structures for particular application which require higher performance with lesser antenna size. Antenna structures are attractive solution for several wireless communication systems, such as base station cellular systems, satellite systems, and point-to-point links.
