Antenna assembly for a vehicle
An antenna assembly includes a base, a modem, a top lid and a housing. The base is composed of an aluminum material. The modem is disposed on the base. The top lid is for the base, and the top lid includes 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.
1. An antenna assembly comprising:
a base, the base composed of a metal material, the base comprising a body, an interior surface, a sidewall and a plurality of heat dissipation elements extending from the interior surface;
a modem disposed within the base, the modem comprising a board, a computation component and a communication chip, the board of the modem directly contacting the plurality of heat dissipation elements;
a top lid for the base, and a multi-band antenna for cellular communications disposed on an exterior surface of the top lid; and
a housing covering the top lid and the base;
wherein the top lid acts as an electro-magnetic barrier for the modem, allowing the modem to be placed adjacent the top lid on a side opposite the multi-band antenna without interference from electro-magnetic signals from the multi-band antenna;
wherein the plurality of heat dissipation elements dissipate heat generated by operation of the modem.
