Model Infinite Ground Plane for Balanced Antennas

Open Live Script

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