TLDR
In this article, a dual-mode compact microstrip antenna based on the fundamental backward wave supported by a composite right/left-handed (CRLH) metamaterial transmission line is demonstrated.Abstract:
In this paper, a dual-mode compact microstrip antenna based on the fundamental backward wave supported by a composite right/left-handed (CRLH) metamaterial transmission line (TL) is demonstrated The physical size and operational frequencies of the antenna are determined by the CRLH metamaterial's unit-cell This antenna is capable of monopolar radiation at one resonant frequency and patch-like radiation at another resonant frequency Numerical and experimental results of a three unit-cell CRLH-based antenna are used to verify the authors' claimsread more

High-impedance electromagnetic surfaces with a forbidden frequency band
TL;DR: In this paper, a new type of metallic structure has been developed that is characterized by having high surface impedance, which is analogous to a corrugated metal surface in which the corrugations have been folded up into lumped-circuit elements and distributed in a two-dimensional lattice.
