Low-height, low-cost, high-gain antenna and system for mobile platforms
First Claim
1. A system that provides information to a second passenger vehicle, to create an information network where there is no existing fixed communication channel between the second passenger vehicle and an information source, the system comprising:
- a first transmitter/receiver unit disposed on a first passenger vehicle and adapted to provide the information to a first passenger associated with the first passenger vehicle;
an antenna coupled to the first transmitter/receiver unit and adapted to receive an information signal that includes the information from the information source and to re-transmit the information signal;
a receiver located on the second passenger vehicle, the receiver being adapted to receive the information signal, and to provide the information for access by a second passenger associated with the second passenger vehicle; and
an additional transmitter/receiver unit that receives the information signal and transmits the information signal, to provide the information signal between the first transmitter/receiver unit and the receiver.

Abstract
A leaky waveguide antenna array that receives and/or transmits electromagnetic signals includes a plurality of radiation waveguides disposed in parallel to each other on a surface plane to form the antenna array. A feed waveguide is located below the surface plane and provides an electromagnetic signal to the plurality of radiation waveguides and/or receives a plurality of electromagnetic signals from the plurality of radiation waveguides and provides a composite electromagnetic signal at an output of the feed waveguide. Each of the plurality of radiation waveguides has a waveguide axis and includes a plurality of apertures arranged in a direction of the waveguide axis. The feed waveguide includes a first section of waveguide having a first end connected to an input/output port. The first section of waveguide has a height substantially the same as the height of each of the plurality of radiation waveguides and the first section of waveguide has a second end coupled to a first junction point. The first junction point transitions from the first section of waveguide to a second section of waveguide and a third section of waveguide that each have a height that is substantially half of the height of the first section of waveguide. The second section of waveguide transitions with an upward sloping ramp to the substantially half height of the first section of waveguide. The third section of waveguide transitions with a downward sloping ramp to the substantially half height of the first section of waveguide.

21. A method for providing information from a source to a second passenger vehicle, the method comprising steps of:
-
transmitting an information signal including the information from the source;
receiving the information signal with a first transmitter/receiver unit located on a first passenger vehicle;
providing the information for access by a passenger associated with the first passenger vehicle;
re-transmitting the information signal with the first transmitter/receiver unit;
repeating the steps of receiving the information signal and re-transmitting the information signal with at least one additional transmitter/receiver unit to provide the information signal between the first transmitter/receiver unit and the second passenger vehicle;
receiving the information with a receiver located on the second passenger vehicle; and
providing the information for access by a passenger associated with the second passenger vehicle. - View Dependent Claims (22, 23, 24, 25)
