Abstract
A resonant waveguide load structure is provided for use in waveguide systems. The load structure includes a length of waveguide which is open at one end and closed at the other end. The load structure also includes a support pin mounted inside the waveguide near the closed end thereof. The load structure further includes a resonant body mounted on the support pin. The load structure also includes at least one spacer member mounted on the support pin for maintaining the position of the resonant body. This load structure may be combined with a waveguide circulator to provide a novel waveguide equalizer apparatus.
