The top lid is for the base, and the top lid comprises at least one antenna element disposed on an exterior surface. The housing covers the top lid and base. The top lid acts as an electro-magnetic barrier for the modem. A communication cable is connected to the modem at one end and extending to and connected to a vehicle internal router with a vehicle modem at the other end.

A door for a smart shipping container includes a door that has an outside skin strengthened by at least one hollow support beam defining an interior channel thereof. The door also includes embedded computing system disposed within the interior channel of the hollow support beam of the door. The embedded computing system includes a power source, memory, at least one processor, communications circuitry, an antenna and one or more sensors. Optionally, a window is defined in the hollow support beam so as to permit access by the antenna to an exterior of the door. For example, the window can be a three-sided window so as to permit access by the antenna to the exterior of the door irrespective of an opened or closed position of the door.

An electronic device of various embodiments of the present disclosure may include a housing, a cylindrical support member disposed in the housing, a first printed circuit board disposed in the housing, a first antenna disposed in the housing, and a first wireless communication circuit disposed on the first printed circuit board. The housing may include a first surface, a second surface parallel to the first surface, and a side surface surrounding at least one portion of a space between the first surface and the second surface. The side surface may include a first side surface and a second side surface forming an angle with the first side surface at a first edge. The first antenna may be disposed adjacent to at least one portion of the first edge and spaced apart from the cylindrical support member by a predetermined distance.

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.
