WAVEGUIDE TRANSITION FOR GENERATING CIRCULARLY POLARIZED WAVES

摘要

Waveguide transitions known in prior art are provided with injection pins which are twisted relative to each other by 90° and by means of which circularly polarized waves are injected into the waveguide. One embodiment of the invention relates to a waveguide transition for a level radar comprising a planar radiator element that cooperates with two lines in such a way that circularly polarized electromagnetic transmission signals can be injected from the lines into a waveguide. There is no need for an additional resonance chamber in the injection zone as the obtained injection is planar.
