Chapter 3 Overview of Microstrip Antenna 3.1 Microstrip Antenna A microstrip antenna consists of conducting patch and a ground plane separated by dielectric substrate. This concept was undeveloped until the revolution in electronic circuit miniaturization and large-scale integration in 1970. The early work of Munson on microstrip antennas for use as a low profile flush mounted antennas on rockets and missiles showed that this was a practical concept for use in many antenna

Chapter 1 Introduction The patch antenna plays a very important role in today’s world of wireless communication systems .There is always a large demand for high performance ,small size and low cost wireless communication systems .in order to get these requirements ,planar patch antenna is preferred because of their various advantages such as light weight ,low volume ,low cost and ease for fabrication .although the microstrip patch antenna has various advantages it has various disadvantages which

The Origin of the universe… The Origin of the Universe by Bilal Qureshi Since the dawn of intelligent man, humanity has speculated about the origins of the universe. There is evidence, which indicates that the universe started around 15 billion years ago. This is probably the
