Corrugate cone horn/circular waveguide converter

Abstract

Abstract PURPOSE:To make small the size of unit, by providing the iris with the converter for the corrugate cone horn and the circular waveguide, so that the synthesized electric field with the TE11 mode wave and TM11 mode wave having the similar electric field distribution as EH11 mode wave can be obtained. CONSTITUTION:A single or a plurality of irises 5 are provided with the conversion section of the corrugate cone horn 4 and circular waveguide 3. That is, since the iris 5 as electric discontinuous section is provided at the waveguide having greater inner diameter possible for the propagation of higher order mode waves, the higher order mode is excited at the part. Further, TM11 mode is generated as the higher order mode and the irises are provided so that synthesized electric field of TM11 mode and the waveguide mode is only Y axis component at the contact surface of the conversion section and the horn. As a result, the electric field equivalent to the EH11 mode wave can be obtained in the horn.
