Abstract: In some embodiments, a computer system chassis comprises a chassis side having an antenna portion and a fan portion. The antenna portion is located closer to an antenna located on an external surface of the chassis side than the fan portion. The antenna and fan portions comprise ventilation holes that provide for the venting of heated air from the chassis interior to the surrounding environment. In some embodiments, the ventilation holes in the antenna portion are thicker than the ventilation holes in the fan portion. The thicker ventilation holes provide an adequate level of EMI shielding for the antenna from platform noise generated by components (CPUs, GPUs, memories, etc.) located in the chassis interior. In other embodiments, the antenna portion comprises alternating positive and negative cross pattern ventilation holes and provides an adequate level of EMI shielding with the antenna portion ventilation holes having the same thickness as the fan portion ventilation holes.

Abstract: Systems and methods are disclosed herein for printed cavities for computational microwave imaging and methods or use. According to an aspect, an imaging system includes a printed cavity having a layer having a first surface and a second surface. The printed cavity defines multiple apertures that extend between the first surface and the second surface. The printed cavity also includes a substrate being attached to the first surface of the layer. The substrate is also configured to be fed a guided wave that excites the apertures to produce a radiation pattern for illuminating a scene. The imaging system also include one or more antennas configured to generate a signal for imaging based on the illuminated scene.
