“…This equivalent circuit is a series R,L,C circuit where the lumped resistance R is proportional to the surface resistance Rs of the patterns, the lumped capacitor C and inductance L account for mutual electric (respectively magnetic) coupling between patches (Fig. 2) [3]. The impedance of the lossy FSS can be written as:…”

A design of ultra wide-band microstrip bandpass filter with tunable notch response of wireless communication system is presented in this paper. The five order bandpass filter is designed using optimum distributed highpass integrated with Defected Microstrip Structure (DMS). The bandpass filter was designed at wideband frequency from 3.1GHz to 10.6GHz. The insertion loss and return loss of this project is set to better than 0.5dB and 20dB respectively. The DMS is implemented in this design in order to remove undesired frequency in wireless communication system. The pin diode is added to act as a switch to tuning the notch response. When the pin diode off, the notch response produce a sharp response at 5.906GHz (WLAN). When the pin diode on, the notch response is removed from the passband and provide full UWB passband. This design is simulated by ADS software and using Roger Duroid 4350B with a dielectric constant of 3.48, substrate thickness 0.508mm and loss tangent 0.0019.

This paper presents compact structure of bandpass filter integrated with Defected Microstrip Structure (DMS) to produce band-pass and band reject response simultaneously. The filter design based upon g0 short-circuited stubs structures of 7 th degree. The narrow notch responses produced by DMS was introduced at a frequency of 5.2 GHz in order to reject any undesired signals which may interfere with the wideband communication systems. The design was simulated and fabricated on a Roger Duroid RO4350 with a thickness of 0.508 mm and dielectric constant, r of 3.48. The group delay in the passband was lower than 0.74 ns. This type of filter is useful in any RF/ microwave communication systems particularly to eliminate any undesired signals in wideband spectrum. While maintaining its excellent performance, the overall physical and cost reduction can also be achieved using this technique.Index Terms-Microwave filter, bandpass, band-reject, Defected Microstrip Structure (DMS), group delay.
