Sketch electric field of beamed antenna.

  1. Sep 10, 2011 #1
    Suppose we have an antenna which has large directional gain. Suppose the antenna broadcasts linearly polarized radiation in a narrow beam and at constant frequency. Sketch the electric field in the plane which contains both the electric field and the beam axis. Does the attached come close?

    Will the magnetic field look similar but rotated a quarter turn about the beam axis?

    Given the electric field work backwards and sketch the vector potential.

    Thanks for any help!
