Abstract :

In applications like wireless communication and satellite communication microwave filter plays a key role. In most communication systems filter performs signal processing i.e. it select required range of frequencies eliminating all other frequencies. While designing these filters using the microstrip lines, the major limiting factors on filter performance are filter bandwidth and group delay. Several types of microstrip filters exist like edge coupled, stepped impedance, hairpin, interdigital etc. These filters have different type of responses by offering trade- off between filter size, bandwidth, reflection, noise rejection, group delay, jitter etc. A new approach in this work will be tried to design a bandpass filter with low insertion loss and high return loss. In this work proposed bandpass filter is designed with Roger material having permittivity εr=10.2 and center frequency=3.5 GHz which is simulated in CST.
