Create antenna array

**Download Required:** To
use this function, first download the WINNER II Channel Model
for Communications System Toolbox™ from the Add-On Explorer. For more information on downloading add-ons, see Get Add-Ons (MATLAB) and Manage Your Add-Ons (MATLAB).

`antArray = winner2.AntennaArray`

`antArray = winner2.AntennaArray(Name,Value)`

returns
a structure representing an antenna array with one isotropic antenna
element. Both the antenna array and the single element have no rotation
and are located at the origin, [0;0;0]. `antArray`

= winner2.AntennaArray

`antArray = winner2.AntennaArray(`

returns
a structure representing an antenna array defined using one or more `Name,Value`

)`Name,Value`

pair
arguments.

For more information, see Antenna Array Model.

Use the `winner2.AntennaArray`

function to
create an eight element uniform circular array (UCA-8) with a 1 cm
radius.

```
UCA8 = winner2.AntennaArray('UCA',8,0.01);
```

Plot element positions

pos = {UCA8.Element(:).Pos}; plot(cellfun(@(x) x(1),pos),cellfun(@(x) x(2),pos),'+'); xlim([-0.02 0.02]); ylim([-0.02 0.02]); title('UCA-8 Element Positions');

Use the `winner2.AntennaArray`

function to
create a two element uniform linear array (ULA-2) with 50 cm spacing
and the dipole elements slanted at +45 and -45 degrees.

az = -180:179; % 1-degree spacing pattern = cat(1,shiftdim(winner2.dipole(az,45),-1), ... shiftdim(winner2.dipole(az,-45),-1)); ULA2 = winner2.AntennaArray('ULA',2,0.5, ... 'FP-ECS',pattern,'Azimuth',az);
