Design and analysis of single patch, 2×1 and 4×1 microstrip antenna arrays

Abstract

Considering the changing trends in communication system, the requirement of a low cost, minimal weight and a low profile antenna is much needed. Therefore, fulfilling the above-mentioned requirements microstrip patch antennas are designed. The objective of this paper is to design a single patch, 2×1 and 4×1 patch antenna array and also analyze their advantages and disadvantages depending upon the results obtained. Antenna parameters such as radiation pattern, antenna gain, directivity and power obtained are studied. The work involves designing of single patch, 2×1 and 4×1 patch arrayat resonant frequency of 2.4GHz. The results are obtained using Advance Design System (ADS).
