Abstract
In this paper, a frequency reconfigurable slot antenna which has a bandwidth-enhanced characteristic is proposed. The proposed antenna consists of two parts; the wide slot and the narrow slot, to increase the bandwidth of the antenna and have the frequency reconfigurable characteristic. The wide slot has triangular shape and makes the bandwidth increased, and the narrow slot can mount PIN diodes. By changing on/off state of PIN diodes, the total length of the slot is changed. From this characteristic, the proposed antenna can finally control the center frequency and minimize variation of the impedance matching.
