📖 This book presents the cost effective methods for designing a rectangular micro-strip patch antenna. In the recent years the development in communication system requires the development of low cost, minimal weight, low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. This technological trend has focused much effort into the design of a rectangular micro-strip patch antenna. In this book, the performance in terms of directivity, radiation efficiency, return loss and radiation pattern of a rectangular micro-strip patch antenna have been analyzed and studied at 3 GHz.
