MATLAB: Patch antenna modelling using phased.Cus​tomAntenna​Element object in phased array toolbox

patch antenna modelling using phased.customantennaelementPhased Array System Toolbox

How can I model a patch antenna with a gain of 9dbi at 5.8GHz using the phased.CustomAntennaElement system Object found in the phased array Toolbox of MATLAB 2014a? I have read the documentation but don't get it right. How do I specify the length, width, Er, etc. Perhaps a simple example will help me. Any help will be appreciated. Thank you.

Hi Frederick,
The phased.CustomAntennaElement is not a physical modeling tool for Antenna. Its purpose is to model the measured field pattern of the antenna rather than the computing the antenna pattern from the physical property such as length, width, current, etc. If you have a measured pattern, or a approximate pattern say using sinc function, then you can import that pattern into CustomAntennaElement.
