Abstract
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.
