Abstract
Antenna systems for receiving transmitted signals comprising at least a first tuned antenna disposed in a known relationship spatially with a second antenna, with the first tuned antenna electrically connected to the second antenna, are disclosed. The antenna system may be configured to allow the antennas to reliably discriminate between left-hand and right-hand polarized circular signals.
