Hello everybody, need help with next problem.
I'm designing patch antenna, freq - 2.6 GHz, using cst mws. The substrate is FR4. The problem is low efficiency i get, about 30%. I thought it was due to losses in substrate, but when i changed tg delta to zero, the efficiency stayed the same. Can anybody tell me how to solve this issue?
