Re: how to verfiy that antenna is resonant and perfecty matc
Hi:
There are mainly 2 types of losses in a typical antenna:
1. Material Loss: It includes conductors, substrates and surface waves. Ideally, surface wave is not material loss. However, surface wave will travel on top of the surface of substraet. It will be absorbed by the substrate eventually in reality because substrates always have loss in reality.
2. Return Loss: It is the loss due to mis-match.
If an antenna is well matched but its maximum gain is low, it means that the antenna has little return loss but much material loss. It is neither a good antenna. Regards.
