Abstract
This article reviews and expands the use of artificial impedance surfaces (AISs), which do not exist in nature but can be synthesized, as ground planes for radiating elements, and in particular, dipoles and loops. It then illustrates that when such surfaces are incorporated with radiating elements, they can enhance the radiation’s characteristics, such as reflection coefficient, gain, realized gain, and pattern symmetry. This is accomplished by the proper design of the metasurface, leading to the enhancement of the radiating elements’ impedance matching, suppression of ground plane surface waves, and reduction of ground plane edge diffractions. These improvements are achieved only over a band-limited frequency range.
期刊介绍:
IEEE Antennas and Propagation Magazine actively solicits feature articles that describe engineering activities taking place in industry, government, and universities. All feature articles are subject to peer review. Emphasis is placed on providing the reader with a general understanding of either a particular subject or of the technical challenges being addressed by various organizations, as well as their capabilities to cope with these challenges. Articles presenting new results, review, tutorial, and historical articles are welcome, as are articles describing examples of good engineering. The technical field of interest of the Magazine is the same as the IEEE Antennas and Propagation Society, and includes the following: antennas, including analysis, design, development, measurement, and testing; radiation, propagation, and the interaction of electromagnetic waves with discrete and continuous media; and applications and systems pertinent to antennas, propagation, and sensing, such as applied optics, millimeter- and sub-millimeter-wave techniques, antenna signal processing and control, radio astronomy, and propagation and radiation aspects of terrestrial and space-based communication, including wireless, mobile, satellite, and telecommunications.
