A Novel Technique for Realization of Circular Polarization in Planar Inverted F Antenna | IJSRD

In this paper various techniques for realization of circular polarization in Planar Inverted F Antenna for Nano satellite applications at 2.4Ghz (s-Band) is presented and several research works done on PIFA are categorized and discussed. PIFA is most commonly used and extensively demanded antenna especially in mobile communication because of its low profile, moderate gain, good radiation pattern, multiband operation.

This  Article represents past study on planar inverted f antenna. After study of various research papers it can be concluded that with the suitable technique circular polarization can be generated in this antenna and thus can be useful in nanosatellite applications

             PIFA can be thought of as a combination of the inverted-F (IFA) and the short-circuit rectangular micro strip antennas. Quarter-wavelength Patch Antenna, which leads into the Planar Inverted-F Antenna (PIFA). It is small and has a low profile, making it suitable for mounting on portable equipment. It is a variant of monopole where the top section has been folded down so as to be parallel with ground plane. This is done to reduce the height of the antenna, while maintaining resonant training length

These are the applications of Planar Inverted F Antenna:

1. Mobile Communication
2. Satellite communication
3. Direct broadcast services
