Abstract

This paper discusses the performance enhancement of conventional two-element antenna array. The study is performed with electromagnetic band gap (EBG) structure loaded in the ground plane of the antenna array. The EBG structure employed consists of an array of swastika slots. The EBG structures possess the property of suppression and passage of electromagnetic waves in certain frequency bands. With the EBG structure, the mutual coupling of the conventional antenna array is reduced to −42.19 dB. Miniaturization of the antenna array is also achieved. An overall bandwidth of 79.72% is achieved with the EBG structure as compared to 3.562% of the conventional antenna array. With the introduction of EBG structure, radiation properties of the antenna array are better. The antenna array designed finds application in the L band of the microwave frequency region. The study has been performed using Mentor Graphics IE3D simulation software, and the measured results have been obtained using vector network analyzer.
