A band-notched ultra-wideband equiangular spiral antenna is presented. With the spiral antenna on the top layer, bottom side is used for a secondary resonant structure to create a notch filter response. VSWR of 2:1 is achieved for the FCC UWB band, which is 3.1 to 10.6 GHz. Notch response is created over the IEEE 802.11a band, 5.15 to 5.85 GHz, VSWR reaching 12:1 at the center of the band at 5.5 GHz. Suppression of radiation in this band is evident in its gain profile over frequency and in current density plot around the resonant structure as well.
