Abstract
In millimeter wave band, the folded waveguide circuit exists some advantages such as wide operating frequency band, high mechanism strength, better heat disspation, easy fabrication and lower cost. It is expected that contradictory between broadband and high power in millimeter wave range can be solved by using the folded waveguide circuit. Computational results of dispersion character and coupling impedance of the folded waveguide are given. It is shown that the folded waveguide has wide bandwidth character in millimeter wave band.
