I thought I would be able to separately simulate the inductor in hfss using some ports, boundary conditions, and solution type, then put it in my antenna design, but I don't know how to do it correctly...
is it possible to measure the natural frequency of the...
Hi everyone,
I am trying to do two-band antenna and use inductor as selective network for frequency separation. And how to specify the natural resonance of the inductor with interturn capacitance, when it similar to parallel oscillating loop?

How to calculate power dissipation in SMD resistor, which is part of the radiating structure, i.e., connected in series with a single-sided PCB (printed circuit board) line. It is clear that P=I2*R, where R is the resistance of the resistor and I is the current through it. But the question is...
Hellow,
How to calculate the free-space field intensity of the antenna in its model - to find the dependence of the absolute values of intensity [µv/m] in the far field (R>> λ) from the angles Θ,φ, and distance R , for example, for a half-wave vibrator, with a known input power?
There HFSS model…

I model shorted stube as a part of the microwave filter. At transition from Layout to Planar EM, the connection between layers Top and Ground is lost. In Planar EM it passes to Assembly Top Layer. How to convert the ideal shunt between layers Top and Ground to real copper bridge: via, some vias...
Dear nvt088,
please explain what is the "reconfigurable radiation pattern", and what antenna options you are interested in - gain, directional characteristics, size, etc ...
and it seems to me that the frequency 400 MHz too low for microstrip technology.

Hi, kavea!
HFSS recommends to use simultaneously with Radiation boundary conditions as also virtual object - (airbox), look for: HFSS Online Help> Technical Notes> The HFSS Solution Process> The Mesh Generation Process
The best regards,

Re: paper request
Yes, it's very hard, really.
But there are many references on this paper at the modern technical literature...
Thanks in advance

I have a similar problem, as in
The question is:
how correctly to define port on single-layered PCB for dipole antyenna model in free space without ground plane using ansoft designer
It seems to me, the input impedance of antenna 0.257 x 50 = 12.85 Ohm on resonant frequency 6.8 Ghz is too...
Re: antennas
Hi electronics_kumar,
you can find a lot of the interesting information on http://www.antennasystem.com/
Added after 1 hours:
and **broken link removed** too
Greetings to all,
I very much need in the help or in managements (manuals) on Optimetrics, as component of Ansoft Designer 1.0 for optimization of linear RF circuits and planar EM design. Please, inform about links, references, or download any managements (manuals), tutorials..
