Hello,
I'm new in antenna simulation world and I would like to ask you some
questions on some topics. I hope someone could help me.
The first question is if it is true that Directivity, Gain and
Efficency of an antenna are simply tied to the her topology and not to
the goodness of the matching network or the source impedance, i.e, if I
have to measure these values, should I necessary verify that the
antenna is correctly matched with source?
Second (and last!) question, I have to simulate a folded dipole with a
ground connection in the center (necessary to the supplying chip as
ground reference). The structure had hence 3 ports. My question is if a
inductive or capacitive load connected to the middle virtual ground
port(and the chip) can significantly affect the matching and other
parameter (D,G) of the port. In few words, that third branch connected
to a virtual ground, how influence the antenna behavior?
Sorry for my trivial questions but I'm continuing studying in order
to fill my gaps.
