Abstract
Metamaterial-based electrically small antennas (ESAs) are gaining popularity in RF communication devices and systems due to their appealing features. This chapter attempts to present a compendious and timely review on metamaterial-based ESAs. The metamaterial has been progressively incorporated in different stage-of-the-art techniques to design more compact antennas to a greater extent keeping their radiation Q-factor, bandwidth, and radiation efficiency in acceptable limits. Planar metamaterial loading has shown simplicity, good performance, and more flexibility in designing ESAs for different RF and mobile communication applications. Different types of planar metamaterial split ring resonators have been used to load the microstrip patch antennas. In this chapter, the basics of metamaterial and an extensive review of metamaterial-based electrically small antennas have been presented. Three configurations of metamaterial-loaded rectangular microstrip ESAs designed by the authors have also reviewed.
