ANTENNA APPARATUS FOR RADIO-FREQUENCY ELECTROMAGNETIC WAVES

摘要

A very flat antenna apparatus (10) for radio-frequency electromagnetic waves has a plurality of individual antenna apparatuses. The antenna apparatus (10) is designed as a transmission type comprising a plurality of planar layers, wherein the antenna apparatus (10) has at least an introduction layer (20), a first phase shift layer (30) with phase shifter devices (32), a radiation layer (60) and a distribution network (36, 58), and wherein the layers (20, 30, 40, 60) are aperture-coupled.
