A Novel Frequency Reconfigurable Slot Antenna Based on S-PINs

A neoteric frequency reconfigurable slot antenna with surface pins(S-PINs) is proposed in this paper. The frequency reconfigurability is achieved by switching the effective length of the radiating slot of the antenna using S-PINs. Compared to the conventional frequency reconfigurable antenna using PIN diodes, the presented antenna with S-PINs is compact and leads a high level of reconfigurable flexibility. By properly changing the states of S-PINs, the antenna can be operated at 6.71/17.58 GHz with a simulated realized gain 1.86/1.47 dBi in the C/Ku-band respectively. The characteristics of the antenna are verified through simulation in this paper which shows that it can be frequency reconfigurable.
