Electronic devices and other apparatuses adapted to receive electromagnetic wave communications are disclosed. An outer housing encloses various device components, including at least an internal antenna located fully therewithin and adapted to receive/send communications from/to an outside source via RF or other electromagnetic waves. A ceramic coating can be a thermal spray coating that covers at least a portion of the outer surface proximate to the internal antenna, and can be “RF transparent”—adapted to allow communications to/from the internal antenna via electromagnetic waves. The outer housing can be plastic, metal or a combination thereof. For metal or other non-RF transparent housings, an RF-transparent insert can be fitted into a window in the housing to permit communications to the internal antenna. The ceramic coating covers some or all of the metal, plastic and/or insert that comprise the outer housing and surface for a final aesthetic finish to the device. |
