Abstract

A communication system for transmitting data between a transmitting platform and a receiving platform moving relative to each other. A circular strip-line transmission line forms the transmitting antenna located on the transmitting platform and a short segment of strip-line, similar in width to the circular strip-line, forms the receive antenna located on the receiving platform. The strip-line transmission line has at least two feedpoints for inputting data and at least two termination points that are terminated with a resistor to ground. The receive antenna is mounted close to the transmitting antenna.

Claims

1. A communication system for transmitting data between a transmitting platform and a receiving platform, the transmitting and receiving platforms moving relative to each other, comprising:

from the at least two feedpoints;

driving means for inputting data to the transmitting antenna;

a receive antenna located on the receiving platform and being maintained a first predetermined distance from a plane of the transmitting antenna; and

receiving means for receiving data from the receive antenna.

2. The communication system as recited in claim 1 wherein the transmitting platform has a top surface made of a dielectric material.

3. The communication system as recited in claim 1 wherein the transmitting platform has a bottom surface including a solid sheet of copper.

4. The communication system as recited in claim 1 wherein the transmitting platform has a bottom surface, and the termination points are terminated with a resistor to the bottom surface of the transmitting platform.
