A Low-Profile Cellular Antenna Module for Vehicular Applications

Since the number of wireless systems integrated into vehicles is increasing, the design of radiating elements and their positioning on the vehicle has become challenging. For this reason, there is a need to find new positions on a vehicle for the antenna elements, different from the typical location on the car roof (e.g. under the plastic shark-fin cover). In this paper, a novel system of 4 low-profile radiating elements for 4x4 MIMO LTE/5G cellular applications is presented to be integrated into a vehicle, for example inside the rear spoiler or under the dashboard.
