Abstract : A miniaturized ultra wideband UWB bandpass filter with improved out-of band performances is presented in this paper. Based on the combination of low-pass and high-pass filters, the UWB filter is realized in a semi-lumped technology using microstrip transmission lines and surface mounted capacitors. In this paper, the filter de-sign rules have been carried out. Furthermore, filters having a 3-dB fractional bandwidth of 142% centered at 0.77 GHz have been realized. Measurements in good agreement with simulations, show attractive properties of return loss |S11|
