A satellite antenna module is disclosed. The satellite antenna module includes at least one antenna element disposed on a ground plane. The ground plane is capacitivly coupled to a vehicle surface. The ground plane is disposed over the vehicle surface at an elevation angle that achieves a higher gain of the at least one antenna element.

Satellite diversity antenna system

An antenna system is disclosed. The antenna system includes at least one first and second antenna. The at least one first antenna is located about a first portion of a mobile structure and is capable of receiving satellite and terrestrial re-transmitted satellite signals. The at least one second antenna is located about a second portion of a mobile structure and is capable of receiving satellite and terrestrial re-transmitted satellite signals. Either the at least one first or second antenna receives the satellite and terrestrial re-transmitted satellite signals and the other of the at least one first or second antenna becomes operative when the satellite and terrestrial re-transmitted satellite signals being received by the at least one first or second antenna is obstructed. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Mobile satellite radio antenna system

An antenna system is assembled to a dielectric medium on a vehicle and is spaced from an electrically conductive member so as to allow for enhanced antenna performance. The dielectric medium has first and second surfaces and a dielectric thickness between the first and second surfaces. An antenna is mounted to the first surface of the dielectric medium for receiving and/or transmitting signals. An electrically conductive member is mounted to the second surface of the dielectric medium for providing a floating ground that forms a capacitive coupling with the antenna. The electrically conductive member is dielectrically isolated from vehicle electrical ground.

Antenna system employing floating ground plane

A combined antenna system used for both vehicles and structures, whereby a satellite antenna is placed concentrically around a conventional mast antenna that can be used for both conventional FM radio and also terrestrial retransmission of the satellite broadcast signals. The combined antenna system, in a vehicle implementation, is configured to use only the one hole created in the vehicle manufacturing process, thereby preventing the necessity of drilling a second hole for the satellite antenna, which alleviates deterioration of the vehicle's body. Additionally, because the combined antenna system can be advantageously placed, a shorter RF cable connecting it to a receiver box can be implemented than otherwise would be the case for a satellite antenna located on a window or roof of a vehicle. In an alternative embodiment, the satellite antenna can be mounted on either a fixed or retractable terrestrial antenna, thereby raising the satellite antenna to a higher elevation with respect to any obstacles on the vehicle or structure.

Combination satellite and terrestrial antenna

An antenna system for a vehicle radio integrated with the defogger heating elements in a window that provides enhanced impedance matching without requiring lumped matching components. The antenna system includes a vehicle window, a conductive grid embedded in the vehicle window and having a plurality of horizontal and generally parallel conductive elements, and first and second bus bars connecting the grid at opposite ends. The antenna system has first and second vertical conductive elements embedded in the vehicle window and arranged substantially orthogonal to the horizontal conductive elements. Tuning elements are coupled to each of the first and second vertical conductive elements and are substantially orthogonal thereto. The tuning elements have a length selected so as to substantially match characteristic impedance of an RF signal path. The horizontal heating elements are engaged for heating the vehicle window during a heating operation, and also serves to receive radio signals for the radio.
