    "voltage gain" Vs "power gain"

    voltage gain to power gain Eactly! On the other hand, power gain(in dB)=2*voltage gain(in dB).

    resonant mode selection for frequency meter?

    There is a paragraph in Pozar's 'Microwave engineering(318, 2nd)': "Since frequency resolution is determined by the Q of the resonator, the TE011 mode is often used for frequency meters because its Q is much higher than the Q of the dominant circular cavity mode. This is also the reason for a...

    HFSS waveport integration line

    integration line for multiple modes In common sense, I think there is no need to assign the integration line for waveports. In this case, HFSS can decide itself.

    loaded antenna simulation in CST

    Yes, it do help. It's too hard to implement a very thin gap to realize an appropriate capacity, so I used lumped capacity, but the obtained result is still not very close to those have been present. Really thanks for help from all of you. It's the best place I have found to discuss and learning.

    loaded antenna simulation in CST

    @purushottam I need to load the antenna with "Wu-king" profile, that is to load the antenna at an equal intervals such that the resistance per unit length varies as a particular funtion of the position along the antenna. I want to not only load it at the port. @adel_48 I tried it, but a problem...

    How to get broadband gain in CST MWS?

    @elektr0 It just means gain information at many frequency points. @eirp It can work, but it cost too much time and not very straightforward.

    loaded antenna simulation in CST

    capacity loaded dipoles Hello,everyone, How to simulate a resistively loaded or capacitively loaded dipole in CST MW v5.0? Never see an example till now. Added after 1 hours 16 minutes: Anyone help?Thanks!
