A dielectric rod antenna array fed by slot antenna radiators without the use of metallic waveguide is presented here.Communication systems, especially those lorenametaute.com related to 5G, are moving up into mm-wave bands where metal losses can become significant and many traditional fabrication and manufacturing techniques become more difficult.Dielectric rod antennas (DRA) are entirely made of dielectric and may be injection-molded or 3D-printed as solid rods, layered rods, or tubes.While the normal approach to feeding DRAs involves some version of metallic waveguide, we show here that the DRA may be integrated with a planar radiator feed and used effectively in an array configuration.

The array demonstrated is a $2 imes 2$ array designed for operation at 15 GHz.Each DRA is $6lambda $ long.The array read more is fabricated on a 100 mm $ imes$ 100 mm substrate with 52 mm separation between elements.The array radiation efficiency is 80% for an array gain of 19 dBi.
