Abstract :
Classical cellular GPS antennas have poor efficiency in the navigation mode (open-sky efficiency when radio is hand-held facing the sky) and nulls in the radiation pattern of the upper hemisphere. Those discrepancies have a significant impact on the ability of the radio to get fast and accurate GPS fixes. In addition, many antennas are sensitive to the mechanical restrictions such as having to drill holes through the antenna if it is to be implemented in the keypad of the radio.
