Hi....
I am working on Microstrip Stacked Patch Antenna for Broadband Application.
In Stacked patch configuration, size of loop in smith chart caused due to coupling between two patches (top and bottom) governs the bandwidth improvement. Tighter the coupling, bigger the loop is and lower the...
Hello Friends,
I am working on Reflectarray Antenna. I want to simulate it using GRASP TICRA. Can anybody please tell me how can I simulate Reflectarray using GRASP TICRA?
Thank you.

Hi...
I tried all the things.....but i am not able to find S Parameters of waveguide......
I have attached the MATLAB file of my code.....can please anybody correct it? I am not able to solve problem........
Thank you...................
Hello Friends,
I am working on tracking antenna for monopulse radar system. I am given specification in term of Tracking Slope......
I generated sum and difference pattern from antenna....but I don't know how Tracking Slope is calculated, what is its significance and what should be its ideal...
hi.......thank you for your replies....
As you said, i will try with dt<dt_max(10%dt_max)......
I am taking 100 samples in one wavelength...wavelength considered here is the minimum wavelength of operation......
For truncation at two faces, I am using Mur's First order ABC.......

Hi.....
I have taken waveguide having cutoff at 3 GHz. I calculated the dimensions of waveguide using the cutoff frequency. I modeled it.
I use dt=dt=1/(c*((1/cell_x)^2+(1/cell_y)^2+(1/cell_x)^2)^0.5);
I sample geometry such that 100 samples can be accommodated in one...
Hi...thank you very much...
I tried xshsren(at)126.com) id......but it is giving me mail failure notice...
I am in good need of 3D FDTD Code for Scattering Matrix.....can you please mail to me on
mevadapratik@yahoo.co.in ?????
Thank you.....
Hi,
I am simulating simple waveguide model using FDTD Method for S Parameter extraction. But, I am unable to simulate it successfully. Output waveform always goes unbounded....and input waveform also does not start properly. It starts with ripples. Is there any solution for this???? If it is...
Hello Friends,
I have simulated microstrip patch antenna on AMC ground plane. I have obtained the improved performance, but i think patch loading on AMC ground plane caused the zero reflection phase frequency to shift. Hence, there is no significant improvement.
Is there any method by which...
Hello Friends,
I have calculated Band Gap for Mushroom Type EBG Structure. But, when I am using that structure for mutual coupling reduction in patch array, I am not getting mutual coupling improvement in complete band gap. Only, for certain frequencies, it gives results.
Is there any reason...
