Abstract
A reconfigurable antenna is an antenna having a capability to modify its properties dynamically in a controlled and reversible manner. The need for multi-functional (e.g., direction finding beam steering, radar, control, and command), high-performance, and cost-effective devices within a confined volume place a greater burden on today's transmitting and receiving systems. So, reconfiguring an antenna is achieved through deliberately changing its frequency, polarization, or radiation characteristics. Many techniques are to achieve this change by redistributing antenna currents and thus altering the electromagnetic fields of the antenna's effective aperture, thereby adapting to changes in system requirements (i.e., enhanced bandwidth, changes in operating frequency, polarization, and radiation pattern). This concept can significantly reduce the number of components, hardware complexity, and cost of the systems. The chapter represents advancement on multipurpose antennas having different applications in communication, broad banding, and detection.
