A previous study of a novel technique to design a band-reject UWB
monopole antenna by using patch loading is extended. Frequency-domain
measurements have confirmed that the antenna designed
using this technique rejects the interfering signal at the two intended
narrow-band frequency ranges. Moreover, the antenna radiation
pattern distortion is negligible except at the notched bands. A study
of time-domain characteristics based on the antenna pulse response
and system fidelity factor is presented. The time performance has
been extracted from frequency-domain measurements using a standard
method. The obtained time-domain results promise the suitability of
the proposed technique to design band-reject antennas useful for
future UWB system applications.
