Reconfigurable Antenna Methodologies and Switch Technologies: A Review

Abstract

Reconfigurable antennas can utilize more efficiently radio frequency spectrum, facilitating a better access to wireless services in modern radio transceivers. This paper presents the concept of reconfigurable antennas and details the emerging technologies that make reconfigurable antennas possible. First, a description of the methodologies available for designing reconfigurable antennas is presented. Then a description of the physical switch technologies and how they can be utilized for antenna design. Their electrical characteristics are described and comparison done between the two technologies.
