Hello,
I am an electronics and telecommution engineer and my major is wireless systems' design. So far I have designed many antennas and their related parts such as filters, matching circuits, power dividers, phase shifters, etc.. I have used CST Micowave Studio Suite and Antenna Magnus most of the time for my designs hence I am quite sure that I can help you with your project. Just let me know and I will do my best to help you.
Best regards
