adding internal port to small loop antenna

AD202606089244

how to add internal port in design of small loop antenna after creating gap in ring structure? even after selecting option of add internal port, it does not get added at the required place..

    In AXIEM, internal ports are not intended to be placed across a physical gap in a structure. An internal port represents an infinitesimally small (zero-length) connection, so it cannot span a real geometric break such as the gap you created in the loop antenna.

    That is why, even after selecting the “Add Internal Port” option, the port does not get added at the desired location across the gap—the tool is behaving as designed.

    Key Points:

    • Internal ports are used to excite or probe current/voltage within a continuous conductive region.
    • They cannot bridge a physical discontinuity (like a gap in a ring or loop antenna).
    • To better understand correct placement and polarity, it is recommended to review the AXIEM documentation on internal ports and refer to the installed example “Dipole Antenna”, which demonstrates proper usage.

    Recommended Approach for Your Case:

    If your goal is to model and excite a physical gap in the loop structure, you should instead use:

    • Differential ports, or
    • Series ports

    These port types are specifically designed to handle excitation across a finite gap and will allow proper simulation of the antenna behavior.

    Thank you very much for your guidance and support through your reply. Apart from internal port, there is only edge port &  point port available in options. I could not see differential port or series port. As per your suggestion I also went through example of dipole antenna and I tried that one. After drawing a rectangle with thick metal layer, I added internal port to that rectangle in between its structure & simulated it. But it is not getting simulated. Kindly guide.

    Refer to AWR Design Environment Simulation and Analysis Guide, to know more about ports and it's Application
