A reconfigurable antenna with switchable multiband functionalities is presented. The antenna operates one at a time at five adjacent frequency subbands in the upper ultrawideband (UWB) frequency band of 6.0-10.6 GHz. The switching from one subband to another is done electronically by means of five PIN diode switches. The antenna also has a nearly omnidirectional radiation pattern, with vertical polarization at each of its frequency subbands. Simulated and measured results are compared and are shown to be in good agreement.
