A Survey on reconfigurable antennas

The study of reconfigurable antennas has made great progress in recent years. Compared with conventional antennas, reconfigurable antennas have more advantages and better prospects. They are lighter in weight, smaller in dimension and lower in price. Moreover, the reconfigurable antennas can provide diversity feature of operating resonant frequency, polarization, and radiation pattern. The latest researches of the reconfigurable antenna are analyzed and summarized in this paper to present the characteristics and classifications.
