The modern microwave and millimeter wave communication system demands good filtering characteristics with compact sizes. In this paper the attention has been given towards the design of a good elliptical lowpass filter with sharp transition between passband and stopband, negligible passband insertion loss and wide stop band. A new defected ground structure (DGS) consisting of two square slots c...

Study on the design of a microstrip monopole antenna as form support and development UWB (Ultra-Wideband) wireless communication devices. The basic concept proposed is minimalist with characteristics operating broadband in accordance those regulated by FCC (Federal Communications Commission). planar type triangular radiation using DGS (Defected Ground Structure) technique for trapezoidal ground...

Ultra-wideband (UWB) microstrip filter design has been proposed by applying defected ground conductor structures designed with the superformula approach. Simultaneously, effects of materials used in designs on properties have examined. After characteristics determined, carried out AWR program. The structure based an 8 GHz center frequency fifth-order Chebyshev ultra-wide bandpass filter. model ...

Filters and other devices using photonic bandgap (PBG) theory are typically implemented in microstrip lines by etching periodic holes on the ground plane of the microstrip. The period of such several holes corresponds to nearly half the guided wavelength of the transmission line. In this paper we study the effects of miniaturization of the PBG device by meandering the microstrip line about one ...

This paper introduces the design of a high-gain wideband microstrip patch antenna for sub-6 GHz 5G communication. The proposed integrates novel defected ground structure (DGS) achieving wide bandwidth. plane uses triangular strip inserted into to improve performance antenna. It also reflective plate concentrate side lobes and minimise production back lobe, thereby boosting main lobe radiated si...

In this study, a novel compact bandstop filter (BSF) by utilizing the defected ground structure (DGS) and microstrip (DMS) techniques are presented. DGS, DMS, compensated capacitors used on both bottom top layers to obtain sharp transition wider stopband. The operating frequency bandwidth of can be comfortably regulated tuning dimensions etched structures. addition parametric studies, an equiva...
