Abstract

This paper presents a novel study on effect of rectangular shape defective ground structure (DGS) implemented on two, four and eight element hybrid microstrip array antenna. The proposed antennas are designed using low cost glass epoxy material. The bandwidth and radiation performance of the antenna is studied and found that as the elements of the antenna are increased, bandwidth also increases by retaining almost the same radiation pattern and gain. Experimentally measured results and design concepts are presented and discussed. These antennas may find application in modern communication system, in radar systems like SAR, monopulse tracking radar and C, X and Ku band microwave applications.
