Detailed Description

Cosine Antenna Model.

This class implements the cosine model, similarly to what is described in: Cosine Antenna Element, Mathworks, Phased Array System Toolbox (Sep. 2020) Available online: https://www.mathworks.com/help/phased/ug/cosine-antenna-element.html

The power pattern of the element is equal to: P(az,el) = cos(az/2)^2m * cos(pi/2 - incl/2)^2n, where az is the azimuth angle, and incl is the inclination angle.

Differently from the source, the response is defined for azimuth and elevation angles between –180 and 180 degrees and is always positive. There is no response at the backside of a cosine antenna. The cosine response pattern achieves a maximum value of 1 (0 dB) at 0 degrees azimuth and 90 degrees inclination. An extra settable gain is added to the original model, to improve its generality.
