[Antennas] Q loaded versus unloaded

Wed, 01 Oct 2003 00:46:15 -0700

Hi,

I'm in the process to understand in detail the basics of antenna theory and=
=20
matching lines (transmission lines) and I have arrived to a point where I=20
am a little bit confused:

Where could I find the difference between Q unloaded and loaded and their=20
effects in the antenna design?

According to what I understood if the Q of a coil in the antenna is very=20
high, the bandwidth decreases and losses too. However in some articles=20
related to tuners I found that coils with low Q reduces losses and it's=20
better to use them ... is the "unloaded" versus "Loaded" present here?=20
Anyone could be so kind to clarify me this point?

(And my apologizes if the question is too obvious or too basic)

Many thanks for your help
