The design of Wireless eXpress band pass filter using a close loop concept

We have proposed a band-pass filter using a close loop concept for WiX(Wireless eXpress) communication system, which is based on the multiband orthogonal frequency division multiplexing UWB system but can transmit and receive datas with more than 3Gbps data rate. The designed WiX band-pass filter composed of outside and inside close loops, and defected ground structure. The outside close loop can be tuned pass band and the inside close loop can be improved insertion loss characteristics. The proposed WIX band-pass filter is obtained with pass band characteristics and good insertion loss.
