  1. Closed: Re: What the effect of size the patch and ground plan on antenna's performance

    Ground plane size affects the antenna performance like gain, radiation pattern and efficiency. As a rule, the ground plane should extend beyond the edges of the patch by at least 2-3 times the board...

    You can write a matlab code for the same. Some reference:
  3. Closed: Re: "Waveguide ports must be aligned with Cartesian coordinate planes" error

    Which simulation software your are using for this design? You can try simulation with lumped port also.
  4. Closed: Re: Regarding 5G antenna types & design guideline if any!

    In 5G instead of radiating energy in all the direction, a group of antennas that’s called Antenna Array, will focus data signal only to communicating device, so signal strength will be very high. ...

    Closed: Re: Directivity of antenna less than 1

    There must be some issue in design setup ( like absorbing boundary conditions) otherwise directivity is always greater than or equal to 1 (0 dB), antenna gain can be less than 1 (0 dB).

    It all depends on your antenna feed network design.
  13. Closed: Re: Problem in placing the waveguide for a CAD model SMA connector in CST

    Select the face of the outer conductor ( or inner conductor) of it and I placed the WG port using this pick. The signal in a coaxial line is defined by the E field in between the two conductors, that...
  14. Closed: Re: Help: EM Simulator package required for designing magnetic coupling

    Also, you can use Keysight's EMPro FEM or FDTD simulator
  15. Closed: Re: Error generating netlist when importing momentum component into schematic

    Also, double check which view of EM component are you using in schematic simulation, ideally it should be emModel

    Closed: Re: drawing coaxial feed for antenna

    Antenna simulation with defined port gives almost same result as port defined at the coaxial input. But defenelty port defined at coaxial input will be more close to real world design.

    Are you using Air as substrate ? Interested of air you can also use low dielectric constant Foam materials.
  23. Closed: Re: Broadside Coupled Balun ADS Port Definition

    You can also try SMD or delta Gap port type then make it diffrential in Schematic simulation if needed.
  24. [SOLVED]Closed: Re: Warning message when converting layout to schematic

    In layout for EM simulation, ground symbol is not required so you can delete these ground symbol in schematic before layout file generation.
