Right Hand Circular Polarized Antenna Modeling and Constriction

Microstrip Antennas became very popular in the 1970s primarily for space borne applications. Today they are used for government and commercial applications. These Antennas consist of metallic patch on grounded substrate. The metallic patch can take many different configurations. However, the rectangular and circular patches are the most popular because of ease of analysis and fabrication, and their attractive radiation characteristics, especially low cross-polarization radiation. The microstrip antennas are low profile, comfortable to planar and non planar surfaces, simple and inexpensive to fabricate using modern printed-circuit technology, mechanically robust when mounted on rigid surfaces, compatible with MMIC designs, and very versatile in terms of resonant frequency, polarization, pattern, and impedance. These antennas can be mounted on the surface of high-performance aircraft, spacecraft, satellites, missiles, cars, and even handheld mobile telephones.
