The basic radiating element is a 1 × 2 Huygens sub-array that consists of two rectangular open waveguides and two plate-shaped dipoles that are virtually short-circuited in between.

Under uniform excitations, the aperture efficiency of the array reaches 97.5% that is very close to the theoretical maximum 100%. This exceptional performance indicates that almost the entire surface is contributing to the co-polarized radiation with ultrahigh aperture utilization rate due to the Huygens radiation effect. To apply this concept into wireless applications requiring low sidelobe levels, an array with tapered excitations achieving sidelobe levels less than -20 dB was fabricated and tested. The achieved realized aperture efficiency is the highest among all previously reported large scale arrays with low sidelobe levels.

Abstract:

This paper presents a 28 GHz Huygens antenna array with ultrahigh aperture efficiency. The basic radiating element is a 1 × 2 Huygens sub-array that consists of two rectangular open waveguides and two plate-shaped dipoles that are virtually short-circuited in between. The sub-array is expanded into a large scale 8 × 16 array that is realized in a full-metal structure. Under uniform excitations, the aperture efficiency of the array reaches 97.5% that is very close to the theoretical maximum 100%. This exceptional performance indicates that almost the entire surface is contributing to the co-polarized radiation with ultrahigh aperture utilization rate due to the Huygens radiation effect. To apply this concept into wireless applications requiring low sidelobe levels, an array with tapered excitations achieving sidelobe levels less than -20 dB was fabricated and tested. The achieved realized aperture efficiency is the highest among all previously reported large scale arrays with low sidelobe levels.
