Device which abstracts and receives microwaves with a physically predetermined radiation pattern and radar device comprising such a device

摘要

Device (100) for the irradiation and/or reception of microwaves and comprising a beam group of u components, u being a straight number, where:The beam group has a sandwich layout with a structured layer (113) with q integrated cavities (111.1) on a side surface (E.1), q being a straight number, and a structured metal layer (112) covering at least part of one side surface (E.1);(i) the sub-components are structurally identical;The metal layer (112) is structured in such a way that each of the u-building blocks includes a suspended patchwork element (201.2) which is enclosed by one of the q-integrated cavities (111.1).The shape and size of the patchy elements (201.2) are defined by the boundary slit (202.2, 203.2) of the metal layer (112),At least one beam group includes a common central feeding point (FP) as an interface for a hollow conductor (150), and the device (100) includes a hollow guide (150) or a wave guide plane connected to the central feeding point (FP).
