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

### View Antenna Geometry

View the physical construction of infinite ground plane reflector antenna.

```figure;show(r); ```

### Calculate Impedance of Antenna

Calculate the impedance of reflector antenna over a freqeuncy range of 800MHz to 1GHz.

```figure;impedance(r,800e6:5e6:1e9); ```

### Plot Radiation Pattern of Antenna

Plot the radiation pattern of reflector antenna at a frequency of 900MHz.

```figure;pattern(r,900e6); ```

### Visualize Antenna Mesh

Mesh and view the infinite ground plane reflector antenna.

```figure; mesh(r); ```
