Hyperfrequency printed card for use in radar, has load collecting signals generated by powerful electromagnetic fields present in vicinity of radar for transmitting heat to metallization layer that covers face of card

摘要

The card has a printed circuit (4) comprising branches. A load (9) is integrated into one of the branches, and collects signals generated by powerful electromagnetic fields present in vicinity of a radar for transmitting heat to a metallization layer (10) covering a face of the card. The load comprises 50 to 90 percent in weight of ferromagnetic material i.e. iron, where the rest of the load is made of epoxy resin or polyimide. Metal holes (12) are formed around the load for constituting a resonant cavity (13). Bottom of the cavity is covered by gold deposit. Independent claims are also included for the following: (1) a method for manufacturing a hyperfrequency printed card (2) a radar.
