This paper presents a high-selectivity compact microstrip bandpass filter (BPF) with a flexibly controllable bandwidth, based on multi-path source-load couplings and a square-type split-ring resonator (STSRR). An STSRR, which is enclosed between the capacitively coupled source and load transmission feed lines, forms the structure of the proposed BPF. The main advantages of the proposed BPF lie in its simple structure and high selectivity due to multiple transmission zeros generated by multipath source-load couplings based on STSRR-enabled magnetic coupling between the feed lines with dual capacitive couplings. In addition, the bandwidth of the proposed BPF can be flexibly controlled by varying the magnetic coupling gap between the STSRR and the feed lines. The measured pass-band insertion and return loss of 0.83 and 27.23 dB, respectively, for a prototype BPF with a central frequency of 3.83 GHz and corresponding bandwidth of 12.98%, demonstrate the validity of the proposed method.

In this paper, microstrip ultra-wideband (UWB) filters using various defected ground structures are studied. Miniature microstrip filters employed in transceiver of modern wireless communication systems play vital role in controlling and regulating frequency response. DGS techniques are etched in ground plane to design compact microstrip based low pass, high pass, bandpass and band reject filters used in modern wireless systems. Various modified and hybrid defected ground structure techniques are employed to achieve high return loss, low insertion loss, ultra compactness, good selectivity and linearity in filters. Study reveals that the proper selection and incorporation of DGS techniques while designing microstrip ultra wideband filter optimizes the various vital parameters which enhances its performance and practicability for various modern wireless communication applications.

In this paper, an interdigital coupled microstrip bandpass filter incorporated with shorted stub multi-mode resonator at ultra-wideband spectrum is presented. Proposed filter is characterized by its ultra compactness achieved through multi-mode resonator. The proposed filter is incorporated with interdigitated transmission line based on Lange Coupler topology. This structure enhances capacitive coupling between feed line and MMR which improves lower frequency selectivity of BPF. The parameters viz. fractional bandwidth of 105%, return loss above 20 dB and insertion loss below 1 dB at centre frequency of 4.875 GHz are recorded. The bandwidth of the filter is measured to be 5.15 GHz (2.3 to 7.45 GHz). The filter shows good linearity with its group delay recorded 0.2 ns with small variations of 0.1 ns at maximum in its passband. The compactness of proposed filter makes it suitable for various modern wireless applications.
