  • Abstract
    In this paper, the resonant disk turnstile is introduced and analyzed. The disk turnstile differs from Dicke´s full-waveguide turnstile in that four of the six ports are coaxial cable ports, yielding a much more compact turnstile, which is easier to construct. The disk turnstile operation is explained as a superposition of the disk TM01 mode (nonradiating) and the disk TM11 mode which couples directly to the circular waveguide (dominant) TE11 mode. A useful operating fractional bandwidth of 3% is possible as compared to a Dicke turnstile bandwidth of about 6%
