I need to do a simulation which is to perform a simulation of antenna parameters
(such as directive gain, beamwidth, radiation patterns, bandwidth, etc.), and i choose the "Multiple-Frequency band antenna". Also i found a software (SuperNEC) to do the simulation, but this software can not simulate this kind of antenna. Can anybody tell me what can i do? Thanks.
If you work with wire antennas, I thinks NEC or its commercial
versions (they are many for example Mininec Broadcast Prof from EM Scientific),
is OK. The program is understandable very quickly.
