“…There have been many designs in practice and all the researchers are working to improve the performance in terms of lowering insertion loss, improving return loss and making sharp cutoff at band width edges [19]. This designed filter uses two adjacently opposite faced coupled half triangular tapered shaped microstrip patch resonators in a parallel cascaded geometry [4], [7], [20]. Filters are used to smooth the communication and to select the required signal over other signals and noise.…”

In advanced communication systems, the filters play an important role in terms of selectivity and rejection of the unwanted signals. In microwave frequency applications the design of filter is difficult as lumped components cannot be used in this range of frequency. Microstrip filters are always chosen over the lumped filters at greater frequency for their higher performance, smaller size, lighter weight and lower cost. In this paper design of parallel grooved band-pass resonator filter has been presented at mid-band frequency 4.25 GHz, which is new concept in filter design. This filter has high attenuation in stop band, return loss of 35.16 dB and small insertion loss of 1.102 dB in the pass band.

Abstract-In this paper, a new microstrip duplexer topology is presented for Digital Communication System (DCS) at 1.8 GHz and for ISM Band at 2.45 GHz. A new approach for the design and the conception of the compact planar duplexer in microstrip technology is proposed. The suggested duplexer is based on two band pass filters (BPFs) using coupled microstrip triangular loop resonators. In this work Electromagnetic (EM) simulation with high meshing density and circuit modeling are achieved to meet some stringent performances concerning isolation, size, insertion loss and return loss.
