The concept of radiation from microstrip antenna was proposed about three decades ago. Because of numerous advantages of these antennas over the conventional microwave antennas like light weight, low cost, low volume, planar structure, conformability to any surface, and compatibility with integrated circuit and solid state devices, such antennas are of great interest for a diverse range of applications in terrestrial and satellite communicatio...

This book deals with the EM analysis of closed microwave cavities based on a three-dimensional FDTD method. The EM analysis is carried out for (i) rectangular microwave ovens and (ii) hybrid-cylindrical microwave autoclaves at 2.45 GHz. The field distribution is first estimated inside domestic rectangular ovens in xy-, yz-, and zx-plane. Further, the RF leakage from the oven door is determined to study the effect of leakage radiation on wirele...

This book focuses on performance enhancement of printed antennas using frequency selective surfaces (FSS) technology. The growing demand of stealth technology in strategic areas requires high-performance low-RCS (radar cross section) antennas. Such requirements may be accomplished by incorporating FSS into the antenna structure either in its ground plane or as the superstrate, due to the filter characteristics of FSS structure. In view of this...
