Outline of Final Research Achievements

A co-planar waveguide feed compact slot antenna with a reflector was developed. The operating frequency depends not only on the slot length, but also the resonance modes between the slotted conducting plate and reflector plate. By adopting an artificial magnetic conductor surface which consists of periodic rectangular conductors as a part of the top layer including the slot, a short range impulse radar antenna was developed.The antenna has a size of 29mmx16mmx1.6mm and 6 dBi constant gain over the frequency range of UWB (Ultra Wide Band) highband from 7.2 GHz to 9.8 GHz.
