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. 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. ## Claims ### Claim 1 An antenna assembly comprising: a base composed of an aluminum material and 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 and on the plurality of heat dissipation elements, the modem comprising a communication chip; a top lid for the base, the top lid composed of an aluminum material, the top lid comprising at least one antenna element disposed on an exterior surface of the top lid; a housing covering the top lid and the base, the housing composed of a polypropylene material; a communication cable connected to the modem at one end and configured to connect to a vehicle internal router at an opposite end; a combiner configured for to input wide area network connection from the vehicle internal router for send and receive data to and from the internet using a 5G communication protocol; wherein the top lid and the base act as an electro-magnetic barrier for the modem; wherein a connection from the vehicle internal router to the modem by the communication cable allows the modem to be located remotely from the vehicle internal router and closer to the at least one antenna element to reduce a connection length from the at least one antenna element to the modem. ### Claim 2 (depends on 1) The antenna assembly according to claim 1 wherein the vehicle internal router is located within a vehicle. ### Claim 3 (depends on 1) The antenna assembly according to claim 1 wherein the base is composed of an aluminum material. ### Claim 4 (depends on 1) The antenna assembly according to claim 1 wherein the base has a width ranging from 2.5 inches to 3.5 inches, and a length ranging from 6.0 inches to 8.0 inches. ### Claim 5 (depends on 1) The antenna assembly according to claim 1 wherein the base has a height ranging from 0.5 inch to 1.0 inch. ### Claim 6 A wireless communication assembly comprising: a base composed of an aluminum material and 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 and on the plurality of heat dissipation elements, the modem comprising at least one of a 3G-5G cellular communication chip, a BLUETOOTH (IEEE 802.15) communication chip, a WiFi (802.11) communication chip, a Global Navigation Satellite System (“GNSS”) reception component, a security access module, or a mobile phone communication component; a router connected to the modem; a top lid for the base, the top lid composed of an aluminum material, the top lid comprising 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, the housing composed of a polypropylene material; wherein the top lid and the base act as an electro-magnetic barrier for the modem. ### Claim 7 (depends on 6) The wireless communication antenna assembly according to claim 6 further comprising a radiofrequency cable connected to the modem. ### Claim 8 (depends on 6) The wireless communication antenna assembly according to claim 6 further comprising a combiner configured to input wide area network connection from the router for send and receive data to and from the internet.
