Dear PlanarMEtaMaterial
i'm interested in MTM and i want to work in that topic
so could you please recommend papers and periodic structures to start with
thanx
hi
i found in some papers for UWB antenna design with slots for frequency notches
that the author represents the slot as a stub either parallel or series
i want to know when i can represent the slot model as parallel or series stubs??
when i can represent it as open or short stub??
and when i...
thank you sir for your reply
i did all what you said
the HFSS give me a plot at the "center frequency only"
but when i changed to sweep to select a desired frequency it doesn't give me any color for the current distribution
it just black
regards
hi :
i'm designing an UWB antena using HFSS v.11
and i want to draw the current distribution on th epatch
i choose field---> then J---> magJ
and i choose the frequency of interset
the HFSS doen't give me that plot
and the icon on the left side is black
could anyone plaese tell me how i can solve...
Re: elevation plane radiation pattern
to chandregowda :
the elevation plane is when phi=0 or 90 while theta is variable
and the azimuth plane is when theta=90 and phi is variable
regards
To WimRFP:
if i have an antenna structure in the xy plane, does the E-field in the z- direction???
and according to that the E-plane is taken to be either xz plane or yz-plane???
H-plane is the xy-plane???
is that correct??
thanks
Hello
I am working on a project of simulating a microstrip antenna to verify the results obtained in a published paper (attached)
I am new to HFSS and I can't excite the antenna to get the published results
I am working on HFSS v11 and have attached the design file I created (there may be errors...
to rotmanlens
i'm new designer in HFSS and i started to simulate square patch antenna with a coxail feed
i took the dimension from a paper
but when i run the simulation the results not look like the paper
i know that the problem is from my own design
i cheched the dimensions and it is ok
and i...
i use this site
https://www.emtalk.com/mpacalc.php?er=2.5&h=3&h_units_list=hmm&fr=2&Operation=Synthesize&La=45.36&L_units_list=Lmm&Wa=46.69&W_units_list=Wmm&Rin=223.730988773
to calculate the dimension of the patch
but the size is different than what appear on the site
which correct???
please reply

hi sir
i'm new in HFSS and i have problem in my design
i want to learn from u
could u please contact me on my email
noor_awad@yahoo.com
i want to attach my file and see ur opinion
please sir
to sweetchoto
i have HFSS version 11
and ur file doesn't open with me
maybe different versions
could u please attach files with version 11 to know how to make waveport cap
please sir
and thanks alot
hi all
i'm new to HFSS and i want to design simple square patch without any modification with coaxial cable according to the dimension given in the paper
"Small Square Monopole Antenna With Enhanced Bandwidth by Using Inverted T-Shaped Slot and Conductor-Backed Plane"
but i don't get the...
