The receiver circuitry for a UWB system is vulnerable to being damaged by strong narrowband signals from nearby sources such as WLAN hubs. For this reason it is necessary to employ some form of filter. In order to save space this filter should ideally be integrated into the radiating element of the antenna. There is a great deal of literature on this topic. This paper announces two new antennas. In comparison with previous work the main advantaging this contribution include 1) the simplicity with which the devices could be redesigned, 2) the high quality factor associated with the notch band, and 3) low level of insertion loss at the centre of the notch band.
