    What does antenna ringing mean?

    Antenna Ringing Could anyone explain what antenna Ringing means ? THanks a lot.

    HFSS--"Interpolating Sweep did not converge"

    wide band simulation on hfss interpolating Hi I am simulating an antenna in the frequency range of 1-10 GHz. I am having my solution frequency at 2 GHz. I am using an interpolating sweep with maximum solutions as 101 and points as 1001. I am getting the error message that interpolating...

    How does Lumped Port work ?

    Hi I have a question. A wave port sends out energy normal to the suface and it is confined in a waveguide. so I could visualise s11 to be the power reflected and reaching the port through the waveguide. But in the case of Lumped port, there are two faces to it, how does it excite and what...

    Ansoft - Differential feed

    Exciting Higher order Modes can be specified when we assign the waveport. And the cutoff frequencies for higher modes can be computed analytically.

    Modelling Coaxial Cable

    Hi Can anyone give a brief procedure of how to model a Coax Cable or send a model Thanks.

    Ansoft - Differential feed

    ansoft differential Hi I am feeding a patch dipole. I need to create a Differential feed. How do I do that in Ansoft (My model has to use Coax feed) Thanks.

    Feeding a Balanced Dipole

    balanced feed for a dipole Hi I want to feed a balanced dipole using coax from underneath. What kind of balun can I use ? and how to implement it in HFSS ? Thanks. Guna

    about antenna bandwidth

    what do you think about the slot and the feed offset ? Also planar inverted cone antennas have very high bandwidth .

    how to use HFSS to simulate such structure??

    ya, a rough sketch would be clear to understand

    has anyone done four tear antenna simulation ?

    2.45GHz F-Antenna query

    f antenna what is your design spec for 2.4 GHz antenna ?

    about antenna bandwidth

    I think you can send your design . you can go for U slot in the centre which gives very high bandwidth. Also the feed has to be slightly offset. Anyway can you upload your design ?

    looking for a demo version @ds

    Re: demo version @ds Is there any demo version of HFSS or Microwave office ?

    Ansoft Hfss - Simulation results ?

    I have found that for designs involving curves , HFSS is much faster than designer. It took almost 3 days for my design to get simulated in designer.
