Patent ID: 8909135

Claim:
An electronic device comprising: a first dielectric substrate; at least a first electronic circuit supported by the substrate, for processing data; at least a first communication unit having a first antenna, the first communication unit mounted to the substrate in communication with the at least a first electronic circuit for converting between a first EHF electromagnetic signal containing digital information and a first data signal conducted by the at least a first electronic circuit, the first electromagnetic signal transmitted or received along a first signal path by the first antenna; and a first electromagnetic signal guide assembly including a first dielectric element made of a first dielectric material disposed proximate the first antenna in the first signal path and having sides extending along the first signal path, and a first sleeve element extending around the first dielectric element along at least a portion of the sides of the first dielectric element, the first sleeve element impeding transmission of the first electromagnetic signal through the sides of the first dielectric element.
