Abstract
An r.f. power distribution network or scanner in which a TEM mode and a pair of selectively phase-shifted TE.sub.11 modes are derived and applied to input ports of a cavity resonator to produce a desired r.f. power distribution at a plurality of output ports. The resonator is in the form of a generally cylindrical member in which the output ports are arranged circumferentially about the periphery and axially spaced from the TE.sub.11 mode input ports. The latter are arranged symmetrically about the TEM mode input port.
