Design of a 3D Printed Omnidirectional Antenna for 60 GHz Application

In this paper, a biconical antenna fed by a rectangular waveguide with a 3D rectangular to coaxial waveguide transition is designed for 60 GHz applications. The proposed transition has a 3D shape that is well suited to be manufactured with a 3D printing process. The antenna provides an omnidirectional coverage in the horizontal plane and works in the frequency band 57.0 to 64.0 GHz. The performances (input impedance, radiation pattern, gain) of the proposed antenna structure are validated by simulations. The finalized structure, after last technical choices, will be manufactured and tested.
