SHORT COINCIDENT PHASED SLOT-FED DUAL POLARIZED APERTURE

摘要

A coincident phased dual-polarized antenna array (300) configured to emit electromagnetic radiation includes: a plurality of electromagnetic radiators (310) arranged in a grid, the plurality of electromagnetic radiators defining a plurality of notches (380); a ground plane spaced from the electromagnetic radiators; a conductive layer disposed between the electromagnetic radiators and the ground plane, the conductive layer having a plurality of slots (330) laterally offset from the notches (380) and being spaced apart from and electrically insulated from the electromagnetic radiators (310); and a plurality of feeds (320), each of the feeds spanning a corresponding slot of the slots (330) and electrically connected to a portion of the conductive layer at one side of the corresponding slot. The feed provides coincident phase centres for both polarisations.
