Patent ID: 8193995

Claim:
An RF system comprising: a metal layer having a first major surface and a second major surface, the metal layer further having a first set of slots oriented in a first direction and a second set of slots oriented in a second direction that is substantially orthogonal to the first direction, the two sets of slots collectively configured to operate as an antenna at a desired radio frequency, wherein each of the slots in the first set of slots and the second set of slots is an opening extending from the first major surface to the second major surface of the metal layer; a silicon layer having a third major surface and a fourth major surface, the third major surface of the silicon layer located substantially parallel to, and facing, the first major surface of the metal layer; and a quartz layer having a fifth major surface and a sixth major surface, the fifth major surface of the quartz layer located substantially parallel to, and facing, the fourth major surface of the silicon layer.
