Active steering dielectric resonator antenna for automotive

摘要

A new active steering broadband antenna system solution for automotive is presented in this paper. The system leverages on the available existing MIMO antenna to provide active steering capability to the main antenna even if the conditions to support MIMO communication are not fulfilled or when the protocol used is not supporting. The antennas are using dielectric resonator structures and multimode radiator elements in order to support all of the most common cellular frequency bands. The active steering capability is achieved by a circuitry controlling the phase and impedance between the main and the MIMO antenna. The simulation results of the prototype are presented and discussed.
