Abstract

In order to cancel unwanted reflected waves in a waveguide system, two micrometer-driven stub tuners are inserted in a waveguide bend. A first tuner is inserted through the outer bend wall to extend axially along one leg of the bend and includes a dielectric rod having a reflecting slug at its tip. Axial movement of the rod permits the variable position of the slug to vary the phase of the wave which it reflects. The second tuner includes a metal rod, which enters the waveguide transversely from the inner wall of the bend, diametrically across from the entrance of the dielectric rod, and permits adjustment of the magnitude of the wave which it reflects.
