Abstract
In this paper, we present a compact Ultra-Wideband band-pass later with notched band at fireless-LAN band using a band-pass and band-notch filter. The structure of our proposed band-pass filter is very simple, and the DGS(Defected Ground Structure) structure is used to get the low-pass filter characteristic, and an embedded open-stub structure is used to get the notched filter. Our proposed band-pass filter can be much smaller than a cascaded filter. As a result of measurement, the insertion loss is less than 0.7dB throughout the pass-band of $2.21GHz{\sim}10.92GHz$, the return loss is more than 17dB and the group delay maximum variation is 0.24ns and a notched band is at $5.3GHz{\sim}5.7GHz$.
