Hi
Did you get some solution to transform the coupling matrix to dimensions like length of resonator and width of iris .. Please let me know the process you followed ??
Thanks
Dear All,
I designed a monopole antenna above the ground plane for frequency of 35 MHz but i am getting problem with the coax at the bottom of ground plane . It is again and again saying Coax and Coax Pin intersects . I am confused with the error so i am attaching my file please help me it is...
No sir i am asking whether HFSS does the same ..Like i am simulating this antenna in HFSS so i am not very clear how does HFSS calculates the S parameter for the array antenna ..This is array antenna only with four arms interleaved and four SMA connectors are there ..
My problem is When i am...
but sir i have 4 sma feeds so Is all the data is going to effect my net effective S parameter or not ? like Z11 Z21 Z31 Z41 is every other Z parameters are also affecting my antennna design ..coz i have 4 SMA feeds ..
Thank you for your reply
I am stucked with my result of the design which i am preparing in HFSS
I am preparing an antenna which is 4 Arm Microstrip Spiral Antenna with 4 SMA feeds at 50 Ohms but since the impedance of antenna as theory says is not equivalent to 50 Ohms So i renormalize it to 300 Ohms Can you please...
Dear frends,

I am preparing an antenna which is 4 Arm Microstrip Spiral Antenna with 4 SMA feeds at 50 Ohms but since the impedance of antenna as theory says is not equivalent to 50 Ohms So i renormalize it to 300 Ohms Can you please check my design and...
Sir,
this is what i did..i make the ports wth a phase delay of 90degree each in clockwise manner for the ports to generate only mode 1 excitation ..that is 0.-90,-180,
-270 degrees in clockwise manner beginning from x axis ..this antenna is expected to give good gain but the gain is negative in...
Sir,
I am very thankful to you for your effort nd time ..it would be grateful if you still look at the file and check out the results for once ..I will also start simulating it ..Sir it seems to be that u hav a gr8 knowledge in this software ...I am fan of you now ..thanks man ...
Sir please...
Sir can u pls send me the corrected file ..i would be thankful to u ...also sir can u pls help me with the radaition box dimensions...
Thank u so much

Sir please send me the corrected file as soon as possible as...
Sir i am simulating 4 arm microstrip spiral antenna ..can u please look at my problem i am not able to get results like good gain , good RHCP ..I think even my antenna is not at all radiating ..what dimensions of rad box i shud look fr ...i would be grateful to you i am attaching file hereby..
