Abstract :
In this paper, a novel method to realize wide-band band-pass filter is presented. The filter is constructed by serial and shunt transmission-line sections and fabricated on multilayer PCB substrates. The frequency response is specified with a pass band of 1.8-5.8 GHz, and with less than 3 dB insertion losses and more than 10 dB return losses in the pass band. Good agreement between the measured and simulated results has been observed. In addition, the transformation models of flexible substrates are also studied by using the 3D electromagnetic simulator. It is shown that the deviations of frequency responses are less than 10% of the unfolded case. Thus, the filter´s structure is suitable for both rigid and flexible substrates
