The `CosineAntennaElement` object models an antenna
with a cosine response in
both azimuth and elevation.

To compute the response of the antenna element for specified directions:

Define and set up your cosine antenna element. See Construction.

Call

`step`to compute the antenna response according to the properties of`phased.CosineAntennaElement`. The behavior of`step`is specific to each object in the toolbox.

This antenna element is not capable of supporting polarization.

`H = phased.CosineAntennaElement` creates
a cosine antenna system object, `H`, that models
an antenna element whose response is cosine raised to a specified
power greater than or equal to one in both the azimuth and elevation
directions.

`H = phased.CosineAntennaElement( Name,Value)` creates
a cosine antenna object,

The *cosine response*, or *cosine
pattern*, is given by:

In this expression:

*az*is the azimuth angle.*el*is the elevation angle.The exponents

*m*and*n*are real numbers greater than or equal to 1.

The response is defined for azimuth and elevation angles between –90 and 90 degrees, inclusive. There is no response at the back of a cosine antenna. The cosine response pattern achieves a maximum value of 1 at 0 degrees azimuth and elevation. Raising the response pattern to powers greater than one concentrates the response in azimuth or elevation.
