Patent ID: 7354311

Claim:
A housing-shaped shielding plate assembly, comprising: an optoelectronic component; and a shielding plate body for shielding said electrical component, said shielding plate body having: a first region disposed inside a metallic structure, said first region having a plurality of wall sections including a rear wall, a first side wall, a second side wall, and an upper side wall that connects at longitudinal edges of the first side wall and the second side wall, wherein the rear wall connects with the first side wall, the second side wall and the upper side wall and at least partially closes the first region of the shielding plate body inside the metallic structure; and a second region inserted through a cutout of the metallic structure, wherein said second region includes a discontinuity through which an emission of electromagnetic waves produced within said shielding plate body occurs; wherein at least one of said plurality of wall sections of said first region of said shielding plate body includes a plurality of elongated openings formed therein, the plurality of elongated openings being slot antennas through which electromagnetic waves produced within said shielding plate body are coupled out of said shielding plate body such that the emission of the electromagnetic waves through the discontinuity is reduced and wherein the electromagnetic waves coupled out through the slot antennas are contained by the metallic structure.
