Abstract
In this paper a broadband transition from coaxial line to circular waveguide has been proposed, developed, and experimentally investigated. The transition consists of series-connected sections-transitions based on microstrip line, antipodal fin line with and without overlapping fins, bilateral fin line, and tapered transition from a rectangular waveguide to a circular one. Taking advantage of fin lines ensures manufacturability and repeatability of the electrical characteristics of the transition. Simulation results obtained are in good agreement with the results of the experimental study. The proposed transition from a coaxial line to a circular waveguide ensures a reflection coefficient of no more than –10 dB in the 8–18 GHz operating frequency range.
