MULTILAYER PRINTED WIRING BOARD RADIATING DEVICE AND PHASED ARRAY ANTENNA USING IT

摘要

This invention relates to a multilayer printed wiring board radiating device. In particular, this invention relates to phased array antennae based on such technology. This invention uses a printed wiring board radiating device more optimised at least in use of available volume by allowing at least some radiators not to be aligned with their respective input/output connectors. The multilayer printed wiring board radiating device according to the invention comprises: a feed layer comprising the feed circuitry; and a radiator layer coupled to the first face of the feed layer, the radiator layer comprising an array of tab radiator elements, input/output connectors for connecting transmitter/receiver modules to their respective radiator elements, and an offset layer for correcting the positional shift due to a non alignment of the radiator with its respective input/output connector, the offset layer being coupled directly or indirectly to the second face of the feed layer.
