Hello ResearchGate community,

I am currently working on antenna simulations and I am in need of guidance regarding the selection of an appropriate antenna simulation tool. My objective is to accurately simulate antenna behavior, obtain power patterns, and determine beam width, depth, and height.

I have previously attempted to use MATLAB's Phased Array System for antenna simulations, but I encountered unexpected results when simulating two antennas with a large spacing between them. Instead of observing two separate beams as expected, I only observed one beam. This raised questions about the accuracy and practicality of using MATLAB's Phased Array System for such scenarios.

Now, I am interested in exploring the use of non-array directive antennas, specifically the Gaussian antenna (spiral Archimedean), to enhance system performance and address challenges such as mutual coupling and sidelobe interference. I want to investigate whether utilizing non-array directive antennas can offer advantages over array-based systems, particularly in terms of system performance improvement, problem-solving capabilities, and the ability to track user movement.

To conduct a comprehensive analysis, I am seeking advice on the most suitable antenna simulation tool. I would like recommendations based on factors such as accuracy, ease of use, versatility, computational efficiency, and availability of advanced features. Additionally, if there are any open-source or freely available simulation tools that can provide comparable results to commercial software packages, I would greatly appreciate knowing about them.

Your insights and recommendations would be invaluable in guiding my research. Thank you in advance for your assistance!

Best regards
