A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the Polarization reconfigurable slot antenna for 5.8 GHz In this paper, a CPW-fed circular polarization reconfigurable slot antenna is proposed. By simply changing the bias status of two PIN diodes through a T-type bias device, the antenna can work as two independent inverted L-shaped slots, and realize reconfigurable performances.

Single-feed Circular Microstrip patch antenna with diagonal slot for polarization reconfigurability has been proposed. PIN diode can be used to achieve reconfigurability by placing it within the slot.
polarization reconfigurable microstrip antenna using PETs was proposed. Either RHCP or LHCP could be obtained by changing the bias-voltage of two PETs at 5.8 GHz. In this paper, a polarization reconfigurable half-mode substrate integrated waveguide U-slot antenna radiating LHCP or LP wave is proposed. Its concept is simple and based on a PIER Letters Online - Reconfigurable Slot Antennas with Based on the CP design, two reconfigurable slot antennas are then developed. One is a frequency reconfigurable antenna, whose CP operation frequency can be switched between two adjacent frequencies. The other is a polarization reconfigurable antenna, whose polarization can be switched between two orthogonal CP senses.
