Abstract: The study of microstrip patch antennas has made great progress in recent years. When microstrip antennas are compared with conventional antennas, the microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, smaller in dimension and ease of fabrication and conformity. Moreover, the microstrip patch antennas can provide dual and circular polarizations, dual-frequency operation, frequency agility, feed line flexibility, beam scanning and omnidirectional patterning. In this paper we discuss about the microstrip antenna and its different types of configurations.
