First Claim
Patent Images
1. A diversity antenna system for use on a vehicle, the diversity antenna system comprising:
- at least two phase diversity antenna elements, where at least one phase diversity antenna element is substantially parallel to a roof surface of the vehicle; and
where the at least two phase diversity antenna elements are adapted to receive phase diversity signals that are processed by adaptive phase diversity technology.

11. A system, comprising:
-
a first phase diversity antenna element; a second phase diversity antenna element; a phase diversity unit adapted to receive a first signal from the first phase diversity antenna element and a second signal from the second phase diversity antenna element; where at least one of the phase diversity antenna elements is disposed substantially parallel to an external roof surface of a vehicle; and where the phase diversity unit is adapted to change a phase of the first signal and output a combination of the first signal and the second signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
