    EBG ground (mushroom structure) in HFSS

    yet not used HFSS........................But Probably u have changed distance b/w the unit cells .............just wondering rather resonent frequency changed or not ?

    ebg structure in simulation

    i m not that much good at it.............But u can use existing discussion over this topic in the forum............................. i m still trying to understand dispersion plots ...................hope u will get it far

    ebg structure in simulation

    using these formulae how u can depict band gap frequencies......... If i m not wrong it requires to plot Dispersion diagram for that.... I m not getting clear idea what r u trying to calculate and why for? 8-O

    ebg structure in simulation

    hey are u working over sm project relates to EBG STRUCTURE which s/w are u using to design periodic geometry? (If possible share sm details)

    ebg structure in simulation

    yes its inverse to cosh why dont u use a scientific calculator it already have this inbuilt function its bit easier to u to calculate

    results of tunable microstrip antenna

    tuning range is the amount of resonant frequency shift could achieve by changing reactance. % bw is{ [higher cutt off frequence (Fh) - Lower cutt off frequency (Fl)]/reasonant frequency of patch (Fc)} X100 (the Fh and Fl values are to be taken on return loss plot at -10dB .while Fc is frequency...

    ebg structure in simulation

    hope this paper (radiation characteristic of microstrip patch over an ebg) will help you to understand a lot.. paper

    metamaterial micostrip antenna using cst microwave studio

    I have try to design mushroom EBG and uniplanar EBG patch antenna .......in IE3D I still not getting clear about how to exactly calculate band gap frequency......... although i have realize that varying parameters such as EBG structure geometry and seperation b/w them result in varying...

    pls some one help to understand EBG and GSPL(grounded surface perturbation lattic !

    some one pls help me differ b/w GSPL (grounded surface pertubation lattice) and EBG:???: I m currently working over EBG microstrip antenna could some one suggest me a good topic related with ebg antenna with application over which i can work thnx
