Design Techniques of Microstrip Patch Antennas: A Comprehensive Survey

Abstract

This paper describes a survey on the microstrip antennas and there historical perspectives. The microstrip antennas have been spaciously studied in the last few decades as one of the standard planar antennas.The microstrip antennas are commonly used in radar and wireless communication systems because they assent pliable orientation of the transmitter and the receiver. Most of them cannot be employed in ultra-wideband (UWB) applications because of their narrow circularly polarized radiation (3-dB axial ratio) and impedance bandwidths. The microstrip patch antenna also have a great possibility for further developments. These antennas are being widely used day by day for various applications in wireless communication systems, GPS and many more applications because of their operation in dual frequency mode or multi-band operations. This survey paper provides a detailed review on the microstrip patch antennas.
