[SOLVED] Antenna Matching using FEKO

[spirited09]

Hi all,

I am trying to do some antenna matching using FEKO for multiple monopoles on a platform. When I match an antenna individually using LC matching or finding the input impedance of an antenna and matching it to 50ohms, the Smith chart shows that it is matched on to gamma=0.

Problems comes when I place 2 or more antenna relative close with their respective matching circuit, the Smith chart then shows that both antenna are no longer matched. Could anyone point me out on what i did wrong? thanks

hi, i guess the reason may be the coupling between the two antennas.
