In this paper, a novel compact frequency-reconfigurable monopole antenna with switchable states including narrowband states, and a dual-band state is presented. Two slot structures are used for finding the configurability of the antenna is achieved by using a switchable slotted structure on the ground plane. The designed antenna has a simple structure and compact size of 40x40mm. The antenna, which supports most applicable frequency bands above 2GHz, can be used in multi-radio wireless systems. Moreover, the proposed antenna, which has a combined UWB and narrowband functionality, has a good potential for use in cognitive radio.
