For designing sub 6 GHz antenna which solver is preferable, FDTD or MoM.

    Hi @Gaayatri ,

    that depends on various criteria. Basically MoM should be well suited. If the model is larger than lambda*4 you can use MLFMM to reduce memory and runtime. But please take care that the frequency range should not be too large (~fmax/fmin <= 3 I would recommend), otherwise the mesh could be too fine for the low frequencies.

    FDTD is generally recommended for very complex geometry and very large Frequency ranges.

    Maybe you can attach the model so I can examine it?

    Best regards,
    Torben
