Create Antenna On Infinite Ground Plane

Create a patch microstrip antenna on a ground plane of infinite length.

p = patchMicrostrip('GroundPlaneLength', inf)
p = 

  patchMicrostrip with properties:

               Length: 0.0750
                Width: 0.0375
               Height: 0.0060
            Substrate: [1x1 dielectric]
    GroundPlaneLength: Inf
     GroundPlaneWidth: 0.0750
    PatchCenterOffset: [0 0]
           FeedOffset: [-0.0187 0]
                 Tilt: 0
             TiltAxis: [1 0 0]
                 Load: [1x1 lumpedElement]
