i have read few papers of yours about AMC ground plane.
I wish to ask you few questions that i hope can clear up my mind.
i) what is the reference value for S11 for AMC unit cells? In some papers i read, the S11 is smaller than -10 dB and some are bigger like -2dB (for instance). But as far as...
Drunkbear: i experience the same warning, may i know how u fixed it? i tried the suggested solution, increase pulse no, but still it doesnt help any.
(i don think this related to accuracy level)

owh so let say that on two axis at -45 degree, then the projection of etheta is -(Etheta/sqrt(2)) right?
and that ephi always have opposite sign (+/-) with etheta? meaning to say, now is +Ephi/sqrt(2)
thx a lot for guidance
dear volker_muehlhaus:
thank for your kind reply....
so its really need 2 ports then..thx for the info...
about the use of simulation of antenna w/out feeding network...i get what you mean...
but, in my case ...my array have 8 elements with 1 single input port...
so what do u think?
erm, maybe...
i think so too (when patches closer , mutual coupling is exist and significant) BUT many papers i read, all of them speaks on mutual coupling describe in S21..as we know, S21 parameter is from multiport applications....
so i totally out of idea, how to calculate/simulate those mutual couplinga s...
hi zorro, thanx again for the reply.
my antenna is dual polarized at an angle of 45 and -45 degree (as in attachment PM to you)...could u give further comment based on the image?
thanx again,
thx so much for the guidance, now i know the co polar component must be allign with the antenna (eg...
thx for your reply,
so i need to take result at angle of 45 degree?
i was following with some paper (dual linear slant 45 degree polarization) where they shown result of co & cross polar at phi = 0 degree.
i never have tots that it shud be presented at the phi of 45,
ok, i will re-upload again...
hi, if i use only one port to excite all my array elements,
so is there any issue of mutual coupling? S21 or S12 is the result of using 2 port feeding, but how bout if using only single port?
i also confius with the terms current density, current distribution and surface current, are they most...
im designing dual linear 45 degree slant polarization antenna array
i get this result of co/cross polarisation as in attachment
is it correct?
first diagram is taken at phi 90degree, while the second is at phi 0degree
i know that co polar shud be greater than cross polar as cross polar is...
hi everyone, i'm currently a postgraduate research student in wireless Communication =]
we are under the same big roof.....Electronics
Nice to meet you all
i encounter the same prob too when im trying to simulate reflection phase diagram, the error mention
"Open pec_ampl_ref_filename For Input As #3"
please assist me on what i can do...
this problem make me headache...
hurm...
(FYI im using CST2010, my window at LAB pc is window XP, and my...
