Reconfigurable Antennas

Abstract

Engineering investigations were conducted in several areas related to the analysis and design of an integrated phased array utilizing microstrip antenna elements. Two types of electromagnetically coupled feed structures for microstrip antenna elements were examined in greater detail. An amplifier design, compatible with the electromagnetic feed, awas synthesized. An integrated active array element with a coplanar waveguide feed was constructed and tested. Preliminary testing of the active element has shown that it has very good performance characteristics. The active amplifier adds 13 dB of gain to the antenna element. A two-element passive array utilizing electromagnetically coupled feeds was also designed, constructed tested. Finally, a rigorous full- wave analysis was made for a circular patch antenna electromagnetically fed with a microstrip line directly underneath the patch. The results show that a properly designed system can have efficient coupling and excitation for the antenna.
