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.
Claims12
An antenna system, comprising:
- an antenna array including multiple conductive antenna elements comprising at least two antennas;
- an array of orthogonal antenna conductive antenna elements disposed at at least two different heights above a ground plane:
- a supporting element;
- a standoff conductive element;
- and
- a ground plane.
3 more elements
An antenna system, comprising:
- a first set of or more antenna elements configured to receive a right hand circularly polarized signal;
- a second set of one more antenna element configured to receive a left hand circularly polarized signal;
- a first output coupled to the first set of elements to provide a first output signal responsive to the right hand circularly polarized signal;
- and
- a second output coupled to the second set of elements to provide a second output signal responsive to the left hand circularly polarized signal.
2 more elements
A locating system, comprising:
- an electronic locating receiver;
- a sonde-beacon;
- a GPS antenna;
- and a GPS receiver module.
