摘要：
A miniaturized ultra-wideband (UWB) monopole antenna with reconfigurable multiple-band notched performance is demonstrated. By modifying the shape of the patch and the ground plane, the UWB operation is achieved. The first and second band-notches are respectively generated by etching a rectangular slot with open ends and a U-shaped slot in the patch, and the third band-notch is produced by loading a C-shaped parasitic element beneath the patch. To realize the reconfigurable band-notched functions, four PIN diodes are inserted in three band-rejected structures. The antenna has a compact dimension of 30 mm x 26 mm. It can switch between a UWB state and several band-notch states by alternating the states of the diodes. Also, good radiation patterns are obtained.
