Development of Electromagnetic Band Gap Structures in the Perspective of Microstrip Antenna Design

Abstract

Electromagnetic band gap (EBG) technology has become a significant breakthrough in the radio frequency (RF) and microwave applications due to their unique band gap characteristics at certain frequency ranges. Since 1999, the EBG structures have been investigated for improving performances of numerous RF and microwave devices utilizing the surface wave suppression and the artificial magnetic conductor (AMC) properties of these special type metamaterial. Issues such as compactness, wide bandwidth with low attenuation level, tunability, and suitability with planar circuitry all play an important role in the design of EBG structures. Remarkable efforts have been undertaken for the development of EBG structures to be compatible with a wide range of wireless communication systems. This paper provides a comprehensive review on various EBG structures such as three-, two-, and onedimensional (3D, 2D, and 1D) EBG, mushroom and uniplanar EBG, and their successive advancement. Considering the related fabrication complexities, implementation of vialess EBG is an attractive topic for microwave engineers. For microstrip antennas, EBG structures are used in diversified ways, which of course found to be effective except in some cases. The EBG structures are also successfully utilized in antenna arrays for reducing the mutual coupling between elements of the array. Current challenges and limitations of the typical microstrip antennas and different EBG structures are discussed in details with some possible suggestions. Hopefully, this survey will guide to increasing efforts towards the development of more compact, wideband, and high-efficient uniplanar EBG structures for performance enhancement of antenna and other microwave devices.

Electromagnetic band-gap structured printed antennas: A feature-oriented survey

“…To understand the effect of EBG phenomenon in the context of improving several performance parameters, authors have gone through the open literature on EBG‐structured printed antennas. To the best of authors' knowledge, only three survey/review articles have been proposed until the date . The EBG technology in the perspective of antennas, Waveguides, and filter configurations has been discussed at microwave and sub‐millimeter wave frequencies.…”

“…The EBG technology in the perspective of antennas, Waveguides, and filter configurations has been discussed at microwave and sub‐millimeter wave frequencies. The survey article has been reviewed based on the current challenges and limitations on different EBG structures in the development of various uniplanar EBG structures. In have been reviewed in the perspective of microstrip antenna arrays incorporated with EBG technology for reducing only mutual coupling.…”

Experimental Analysis of a Directive Antenna with a 3D-EBG Superstrate

“…Electromagnetic band gap (EBG) materials [1] can be successfully employed to improve the performance of antennas [2], [3]. When used as planar reflectors [4], substrates [5], or high-impedance ground-planes [6], are able to eliminate the drawbacks of conducting ground-planes, to prevent the propagation of surface waves also allowing a lowering of the antenna profile, and to improve the radiation efficiency.…”

Modeling of electromagnetic band gap structures: A review

“…Such a review is rarely proposed in the open literature to the best of authors' knowledge. This review article in parallel to other referenced review articles may be considered equally useful for the antenna researchers working on EBG structures as well as EBG‐structured antennas/filters. The review article is summarized as follows: The EBG structures using analytical methods are described in Section 2. The numerical modeling of EBG structures is then discussed in Section 3. Section 4 outlines a summary of the review process.…”

“…The review/survey literature on the modeling of EBGstructures in the last decade is very much limited. [36][37][38] Maagt et al 36 have reviewed the literature of EBG technology, in particular for application domain in the microwave and (sub) millimeter wave frequencies. Bhasveer and Singh 37 have reviewed the literature on EBG structures for array antenna applications only.…”
