Summary
| Description |
English:
Diagram of a thought experiment used to derive the
effective aperture
of a
isotropic antenna
, used to derive the expression for antenna gain. It consists of an ideal lossless isotropic antenna
A
in a
thermal cavity
at temperature
T
, connected through a lossless
transmission line
and a narrowband
filter
F
to a resistor
R
in another cavity. Both cavities are at the same temperature and so are in
thermodynamic equilibrium
