857.~.~ Coupling at spaced points on antenna


DEFINITION

Classification: 343/857

(under subclass 850) Subject matter wherein the coupling network includes a plurality of electrical paths, which may include a balanced path, connected to physically spaced points on the active portion of the antenna.

SEE OR SEARCH THIS CLASS, SUBCLASS:

731+, and 739+, for antennas with energy absorbing means remote from the feed line coupling or with feedback coupling which may be coupled to plural points of the active portion of the antenna.

743, for high frequency loop type antennas which involves coupling to spaced points on the loop.

793+, for dipole antennas which may involve connections to spaced points on the active portion of the dipole.

858, for antennas having a coupling network including plural paths coupled respectively to more than one termination.
