Abstract

An antenna circuit, a method of manufacturing, and a method of operating the same are provided. An antenna member, a first dielectric layer, a top ground plane, a radiating slot ring through the top ground plane, a second dielectric layer, a stripline feed member, a third dielectric layer, and a bottom ground plane are all laminated together within a specified arrangement to form an efficient multi-band micro-strip antenna circuit. A micromachined electromagnetic switch is utilized to alter the length of the antenna member, thereby producing resonant frequencies which correlate with those radiated by the ring slot.
