.~ With variation of antenna impedance or dimension for modulation
DEFINITION
Classification: 455/107
With variation of antenna impedance or dimension for modulation:
(under subclass 91) Subject matter where the carrier wave is modulated, under control of the modulating intelligence
signal, by varying the impedance or dimension of the antenna.
SEE OR SEARCH THIS CLASS, SUBCLASS:
121+, for systems in which the antenna circuit is varied for tuning.
129+, for systems in which the antenna coupling is explicitly shown and varied therefor.
269+, for systems of antenna combined with receiver for similar coupling arrangements, noting especially 289.
