In this paper, we investigate the signal bit error rate (BER) characteristics of a vehicle-borne weighted polarization maximum ratio combining adaptive array antenna for secure communications. The array comprises orthogonally arranged dipole elements, which are combined using weight functions determined by the cross-polarization power ratio in the propagation environment and the angle of inclination of the antenna. The experimental results show that the required signal-to-noise ratio for the proposed antenna to achieve the prescribed BER is lower than that for a conventional dipole array even in vehicle rollover accidents.
