Antenna device and aircraft/spacecraft

Abstract

The invention concerns an antenna device (1) for transmission and reception of microwaves with controllable multi-beam directionality, comprising: a base body (2), which comprises at least one plate-shaped module (3) as a first type and at least one further plate-shaped module (4) as a second type, the first module(s) (3) and the second module(s) (4) being stacked on top of one another and their end faces (5-8) taken together defining side-surfaces (10-12) of the base body (2), wherein each module (3, 4) comprises at least one transmission side-surface (14, 16, 43) as an end face thereof (5-8), each transmission side-surface (14, 16, 43) of each module (3, 4) comprises a plurality of antenna elements (13), the first module(s) (3) and the second module(s) (4) are arranged such that one transmission side-surface (14, 43) of the first module(s) (3) is part of a first side-surface (9) of the base body (2) and one transmission side-surface (16, 43) of the second module(s) (4) is part of a second side-surface (10) of the base body (2), the first and second side-surfaces (9, 10) of the base body (2) being different, and each transmission side-surface (14, 16, 43) of each module (3, 4) defines, via its antenna elements (13), an antenna array. The present invention also concerns an aircraft or a spacecraft, especially a satellite (100), comprising the antenna device (1).
