Reconfigurable Ground-Slotted Patch Antenna Using PIN Diode Switching
Seung-Bok Byun, Jeong-An Lee, Jong-Hyuk Lim, and Tae-Yeoul Yun
Abstract :	This letter presents a reconfigurable ground-slotted patch antenna using a PIN diode connection in slots to achieve dual-frequency operation. Slots in the ground plane increase the electrical length and thereby reduce antenna size by 53%. By controlling PIN diode conduction, we achieved band hopping while still satisfying the bandwidth requirements for K-PCS and WiBro bands.
Key word :	Frequency-reconfigurable, K-PCS, PIN diode, WiBro.
