Abstract
Recently, the demand of information and telecommunication systems has been growing rapidly. In order to realize these systems with small, lightweight and multi-function capabilities, planar circuit and antenna technology have been used. However, these technologies have problems such as low gain and surface wave loss. Photonic band-gap technology is believed to be a promising new solution to these problems. In this paper, simulation results using the FDTD method for photonic band-gap structure on a microwave and a millimeter wave circuit substrate made by etching are presented. The analysis of a Microstrip line and a millimeter wave active integrated antenna with PBG structure are also presented.
