Hi,
i have a question about an equivalent circuit.who
can help me?
we know that the equivalent circuit of centered post(aligned
parallel to the electric field) in rectangular guide is: two capacitive
reactance elements aparted by a inductive reactance element (paralleled
to ground) but,if the centered post is part of coaxial line connected
to the wavguide,suppose that the other terminal of coaxial line is short.what's
its equivalent circuit?,only connected with coaxial line shorted another
side? Mr J.F.White did that in 7th chapter of his book microwave semiconductor
engineering.
when i ues the equivalent circuit in ADS ,the result
is different from which simulated in CST microwave studio and ansoft
HFSS.
I am puzzled,
note:
1.the structure is not the coaxial-waveguide
transition we always mentioned
2.coaxial line(ordinarily air filled)
