Abstract

A planar dipole UWB antenna with an integrated filter to notch out the GPS frequency band is presented. The notch filter comprises lumped and distributed capacitors and inductors, which are integrated on the substrate close to the feed connector. Measurement results show that the gain of the GPS notch antenna is practically the same in the UWB pass band, but it is lower by 20 dB or so in the GPS band compared with the generic printed dipole antenna. Although the amount of suppression for GPS frequency components by the antenna alone may not be enough to satisfy the UWB emission limit, it can certainly relieve the performance requirements on a separate GPS notch filter.
