Dielectric Rod Antenna Array With Planar Folded Slot Antenna Excitation

A dielectric rod antenna array fed by slot radiators without the use of metallic waveguide is presented here. Communication systems, especially those related to 5G, are moving up into mm-wave bands where metal losses can become significant and many traditional fabrication manufacturing techniques more difficult. Dielectric antennas (DRA) entirely made may be injection-molded or 3D-printed as solid rods, layered tubes. While normal approach feeding DRAs involves some version waveguide, we show here that DRA integrated with a planar radiator feed used effectively in an configuration. The demonstrated 2 ×2 designed for operation at 15 GHz. Each 6? long. fabricated on 100 mm × substrate 52 separation between elements. radiation efficiency 80% gain 19 dBi.
