Create Antenna On Infinite Ground Plane

Create a reflector antenna on a ground plane of infinite length.

r = reflector ('GroundPlaneLength', inf)
r = 

  reflector with properties:

              Exciter: [1x1 dipole]
            Substrate: [1x1 dielectric]
    GroundPlaneLength: Inf
     GroundPlaneWidth: 0.2000
              Spacing: 0.0750
      EnableProbeFeed: 0
                 Tilt: 0
             TiltAxis: [1 0 0]
                 Load: [1x1 lumpedElement]
