Design consideration of Microstrip Patch Antenna

The study of microstrip patch antennas has made great progress in these days. This is mostly due to their versatility in terms of possible geometries that makes them applicable for many dierent situations. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects like low cost, lighter in weight, low profile, smaller in dimension, low volume and conformity and ease of fabrication. Theses microstrip patch antennas can provide dual-frequency operation, dual and circular polarizations, feedline flexibility, frequency agility, broad band-width, beam scanning omnidirectional patterning. In this paper we discuss the microstrip antenna, feeding techniques and application of microstrip patch antenna with their advantage and disadvantages over conventional microwave antennas.
