Abstract: Antennas with dynamically choosing functionalities are the future demand for an efficient wireless communication system. Reconfigurable antennas are having such function to satisfy the need. It provides flexibility in frequency, pattern and diverse polarization. When compared to frequency and pattern reconfigurable antennas, polarization reconfigurable antenna provides better results while considering extenuating the losses due to multi channel transmission. Latest researches based on polarization diversity antennas are described in this paper to present the classifications.
