Abstract :
Antenna miniaturization with enhanced radiation performance is a contemporary problem with application in RF and wireless systems. The substrate and ground plane of the antenna play a very important role in achieving the desired antenna characteristics. The focus in this paper is to present the application of two types of meta-substrates for novel antenna designs, namely, embedded-circuit meta-material (ECM) and reactive impedance surface (RIS) substrates. ECM provides a way to fabricate an ε-μ substrate, and allows antenna miniaturization with relatively high bandwidth and efficiency. Also, a novel compact RIS as the ground plane for a dual-band E-shaped patch/slot antennna is proposed, to reduce th interaction of the antenna with its ground and design a miniaturized wideband antenna system.
