Abstract
The invention provides for the reception of a L-band signals and MF-band signals using a single antenna element by employing an L-band antenna in conjunction with a connection cable that acts to receive MF-band signals, the invention further providing for the isolation of the L-band signals from an MF-band processing path and isolating the MF-band signals from an L-band processing path.
Claims20
A method for receiving L-band signals and MF-band signals, comprising the steps of:
- providing an L-band antenna for receiving an L-band signal;
- providing an electrical connection for coupling the L-band signal from the L-band antenna to an L-band processing path and for receiving MF-band signals;
- coupling MF-band signals received by the electrical connection to an MF-band processing path;
- and
- summing the L-Band and MF-Band signals.
An apparatus for receiving L-band signals and MF-band signals, comprising:
- an L-band antenna for receiving an L-band signal;
- an electrical connection for coupling the L-band signal from the L-band antenna to an L-band processing path and for receiving and coupling MF-band signals to an MF-band processing path;
- and
- summing the L-Band and MF-Band signals.
A method for receiving L-band signals and MF-band signals, comprising the steps of:
- providing an L-band antenna for receiving an L-band signal;
- providing an electrical connection between a first conductor and an active element of the L-band antenna and providing an electrical connection between the first conductor and an L-band processing path;
- providing an electrical connection between a second conductor for receiving MF-band signals and a ground of the L-band antenna and providing an electrical connection between the second conductor and an MF-band processing path;
- providing substantial isolation of the MF-band signals from the L-band processing path and substantial isolation of the L-band signals from the MF-band processing path;
- and
- summing the L-Band and MF-Band signals.
