Model Infinite Ground Plane for Balanced Antennas

This example shows how to model an infinite ground plane and calculate fundamental antenna parameters for balanced antennas.

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: [1×1 dipole]
            Substrate: [1×1 dielectric]
    GroundPlaneLength: Inf
     GroundPlaneWidth: 0.2000
              Spacing: 0.0750
      EnableProbeFeed: 0
            Conductor: [1×1 metal]
                 Tilt: 0
             TiltAxis: [1 0 0]
                 Load: [1×1 lumpedElement]
