Patent attributes
A Global Navigation Satellite System (GNSS) receiver for a portable device includes a first linear polarization antenna configured to receive a first linear polarization component of a GNSS signal; a second linear polarization antenna configurable to receive a second linear polarization component of the GNSS signal, a radio frequency signal conforming to a second wireless communication technology, or both; and a hybrid coupler that combines the first linear polarization component of the GNSS signal and the second linear polarization component of the GNSS signal to generate a circularly polarized GNSS signal. In some embodiments, the GNSS receiver includes a tuner to tune the resonant frequency of the second linear polarization antenna. In some embodiments, the GNSS receiver includes a switch or a filter to connect or disconnect the second linear polarization antenna from the hybrid coupler to implement a circular polarization antenna or a linear polarization ante.
