## Abstract

A mobile device may include a first antenna positioned on a first substrate, the first antenna in communication with a global navigation satellite system (GNSS) receiver to receive first radio signals from at least four GNSS satellites and convert the first radio signals into first electronic signals and a second antenna positioned on a second substrate between 30 degrees and 90 degrees from the first antenna. With such multi-band antenna design, arrangement, and positioning, the GNSS receiver may maximize the number of satellites it can track which results in improved geometry of tracked satellites, which reduces dilution and precision and improves location accuracy of the GNSS receiver.
