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.
