In this paper complete literature review of reconfigurable antennas is presented. In recent years the study of reconfigurable antenna in communication field has made great progress. Reconfigurable antenna provides selectivity in frequency, bandwidth, polarization and gain with small dimension, light weight and low price. The demand of reconfigurable antennas has increased drastically in multi-band systems, satellite communication, and mobile communication applications. The researches on this antenna are summarized and analyzed from literature.
