Transmission stack for extremely high frequency wireless communication
First Claim
1. A mobile device to communicate with a mobile device accessory at extremely high electromagnetic frequencies, the mobile device comprising:
- an extremely high frequency transceiver communicating within 30 GHz to 90 GHz range, the extremely high frequency transceiver associated with the mobile device transmitting 30 GHz to 90 GHz electromagnetic frequencies through a region of a chassis of the mobile device to a second extremely high frequency transceiver associated with the mobile device accessory;
the chassis of the mobile device comprising a ceramic material forming the region of the chassis of the mobile device, a thickness of the ceramic material in a range between 0.03 mm and 1.5 mm, inclusive, creating a standing wave of the 30 GHz to 90 GHz electromagnetic waves passing through the ceramic material; and
a dielectric member comprising;
a layer of foam having a thickness between 0.7 mm and 7.9 mm, inclusive;
a layer of glue having a thickness between 0.4 mm and 5.4 mm, inclusive; and
a layer of plastic having a thickness between 0.46 mm and 7.1 mm, inclusive.

Abstract
Disclosed here are systems and methods which enable high-bandwidth communication between a mobile device and an accessory. The high-bandwidth communication uses electromagnetic waves in the extremely high frequency range between 30 GHz and 300 GHz inclusive, also known as millimeter waves. The millimeter waves travel through at least the chassis of the accessory and the chassis of the mobile device without significant scattering and attenuation. The properties of the materials through which the millimeter waves travel determine the attenuation of the millimeter waves. Disclosed here are various materials, and their thicknesses, which form a transmission stack through which the millimeter waves can travel unimpeded. In effect, the transmission stack acts as a dielectric member which facilitates the transmission of the millimeter waves, while attenuating transmission of waves outside of the extremely high frequency range.
