In line e-probe waveguide transition

Abstract:

A transition device for a hollow waveguide comprises a rectangular structure comprising an inlet wall and interior extending from the inlet wall along a longitudinal axis. The inlet wall is configured to receive a transmission line comprising an antenna. The antenna forms a proximal end proximate to the inlet wall and a distal end configured to extend into the rectangular structure of the hollow waveguide. A channel is formed in the rectangular structure. The channel comprises a base forming a tuning surface. The tuning surface is configured to extend along a length of the antenna in a spaced configuration parallel to the longitudinal axis.
