Multibeam antenna using cavity‐based waveguide structure with extended hemispherical lens at millimetre wave

Abstract A multibeam antenna with a single input port using a cavity‐based waveguide structure is implemented. The proposed structure uses a cylindrical cavity and a higher‐order TM21 mode is excited in it. The higher‐order mode is to divide the incoming power in three different directions. The beam...
