摘要：
A multi-frequency reconfigurable antenna is proposed. The designed antenna can be electronically tuned to achieve the tuning operation in the 2.4GHz band defined by the IEEE 802.11b standard and the ultra-wideband (UWB) low frequency. An L-shaped branch and a polygon patch are used as the main radiators of the antenna. Two varactor diodes are mounted on the slots and one PIN diode is mounted on the L-shaped branch to vary the effective electrical length of the antenna. The simulation and measurement results match well. With high frequency reconfiguration stability under guaranteed miniaturization, good impedance matching (S11 > - 10 dB) is obtained in several operating bands, and the overall impedance bandwidth covers 2.34-2.58 GHz and 3.11-5.14 GHz. It provides solutions for operation within WiMax, WLAN, and 5G-sub6 GHz.
