Abstract:
1. An isolated dual-mode converter comprising: a first waveguide element comprising a circular waveguide, and N rectangular waveguides each having a first end being connected to a side surface of the circular waveguide in a manner such that the N rectangular waveguides are arranged evenly and radially, and a symmetrical axis of an opening at the first end are arranged parallel to the axis of the circular waveguide; and a second end, wherein the second ends of the N rectangular waveguides become at least a first in/out port and N is an integer greater than 1; and a second waveguide element comprising an outer conductor and an inner conductor defining a coaxial waveguide, and an insulating filler disposed therebetween, wherein the second waveguide element is connected with the first waveguide element in a manner such that an end of the coaxial waveguide is aligned axially and connected with an end of the circular waveguide, the other end of the coaxial waveguide is a second in/out port, and the other end of the circular waveguide is a third in/out port.
