Hi,
I was wondering if someone could play with my project and tell me why I can not get S11 better than -10.1 dB ? Is it because of the radiator geometry or the project is set up wrong.
I have parametrized my drawing and I have been varying b and probes location radius during parametric sweeps but... all I get is -10.1 dB (@ 49.89 Ohms of port Input Impendance && -7.73 reactance ). I do not know how to get rid of imaginary part, it always has some magnitude.
this is 1.57542 GHz gps antenna, rhcp.
Would appresiate any feedback,
Thanks.
