Varactor Diode Loaded Reconfigurable Patch Antenna with Adjustable Slots
Reconfigurable antennas play an important role in modern wireless communication systems, such as Personal Communications Service (PCS) and Wireless Local Area Network (WLAN). A varactor diode is placed on every slot to alter the current direction, which determines the polarization state. The influences of the slots and varactor diodes on antenna performance are minimized because the slots and diodes are not on the patch. The simulated results verified the effectiveness of the proposed antenna configuration. A variation in parameters like RL, gain and radiated power is achieved.
