Patch antenna modelling using phased.CustomAntennaElement object in phased array toolbox
显示 更早的评论
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.

If you want to actually model the patch antenna, it's better to use the Antenna Toolbox (not sure if it's in 2014a or how different it is compared to the most recent version). If you look at the url below, you can see there's a whole list of functions and objects specifically for patch antennas.
The CustomAntennaElement system object is better used when you already have the magnitude/phase patterns from the antenna, as the patterns are the main input into the object.

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.

Yes it is possible if you export it to a csv file or something like that. Here is an example in the product that shows a similar workflow so you may want to take a look? If you have any question, I'd be more than happy to help.
