Abstract
A Global Navigation Satellite System (GNSS) electronic circuit is described that uses an antenna and a fractal ground plane conductor or a fractal counterpoise. Some embodiments of the electronic circuit include a first ground plane conductor portion on a first electronic substrate, and a second ground plane conductor portion on a second electronic substrate. The second ground plane conductor portion is shaped to include at least one fractal pattern. The fractal pattern of the second ground plane conductor portion makes the ground plane seem electrically larger than it is. The fractal ground plane conductor portion minimizes the reception of GNSS satellite signals below the antenna, and improves the reception of signals from low elevation GNSS satellites above the horizon.
