    Closed: how to check beamwidth

    Hello all,
    I simulated circular polarized circular microstrip antenna in IE3D.
    I am attaching .geo file can anybody tell how to measure beamwidth? Simulation frequency band- 2.25 GHz to 2.65 GHz

    Closed: Re: Patch antenna Coax feed

    Generally feed point is on the axes. If u have cutted geometry then feed point may get shifted. If antenna is not perturbated then try feed point on x-axis.

    Send me resonant frequency. I'll let u know actual patch radius.

    Added after 2 minutes:

    Actually there is no such formula to determine actual radius. We have to solve for different values...
