This paper aims to analyze the effect of application of defected ground structure (DGS) on the resonating properties of microstrip patch antenna. In order to obtain the comparative results a small size DGS has been introduced in the ground plane exactly under the feeding strip of the patch antenna. The representative results obtained from the simulations have revealed that the proposed antenna ...

This paper describes the effect of inserting a rectangular shape defected ground structure (DGS) into the ground plane of the conventional rectangular microstrip patch antenna (CRMPA). The performances of the CRMPA are characterized by varying the dimensions of the rectangular slot (RS-DGS) and also by locating the RS-DGS at specific position. Simulation results have verified that the CRMPA inc...

A broadband compact Y shaped monopole antenna with band-notched characteristics is designed and investigated. The structure based on the defected ground slit resonating structures. plane loaded two hook slots opposite edges along its width. One horizontal slot one vertical are also etched to improve impedance matching for design resonate in WiMAX WLAN wide bands. It operates at frequencies of 2...

A bandpass negative group delay (NGD) passive circuit based on defect ground structure (DGS) and substrate integrated waveguide (SIW)-matched is developed in the paper. The NGD DGS topology originally built with notched cells associated self-matched elements. design method introduced as a function of geometrical SIW via Then, parametric analyses full wave 3-D electromagnetic <tex xmlns:mml="htt...
