Abstract
An arrangement of MIMO antennas in a vehicle, such as an automobile, where at least one of the MIMO antennas is placed inside the vehicle in the richer multipath signal propagation environment. The MIMO antennas will include a primary MIMO antenna that may also be used for non-4G cellular services and one or more secondary MIMO antennas that are used only for 4G cellular services. In one embodiment, the primary MIMO antenna is mounted to a roof of the vehicle in a module including other antennas and the one or more secondary antennas are positioned at desired locations within the vehicle. In another embodiment, the primary MIMO antenna and the one or more secondary MIMO antennas are all positioned within the vehicle.
