Active and electronic scanning type network antenna for use in radar, has microwave frequency distribution channels linked between distribution unit and module, each having distribution sub channels to transport signal to radiating element

摘要

The antenna (ANT) has a microwave frequency distribution unit (MDI) placed along a mother card (CM) to distribute a signal to be transmitted and received. Plates (PL) i.e. beams, are parallel to each other and fixed perpendicularly to the motherboard. Modules (MOD) are placed along each support and include a number of radiating elements (ELR). Microwave frequency distribution channels (VDI) are coupled between the unit and one of the modules, where each channel has distribution sub channels incorporated within the module to transport a signal towards the element.
