Applying electric-magnetic-electric (EME) composite metal strips to reduce the size of patch antennas

Abstract

This paper presents a novel technology to reduce the size of microstrip patch antennas. Utilizing this recently developed periodic structure (EME metal strips), we can increase the slow-wave factor of microstrip lines. This benefit can help us to reduce the size of patch antennas. According to our experimental results, the resonant length and area of the EME patch can be reduced to be 76% and 57% when compared with the conventional one.
