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.
