Abstract
Disclosed is an energy coupling device which can be used with metrical and decimetrical waves. To distribute, equipotentially and in equiphase, towards n users, the energy coming from m equipotential sources in equiphase, a 90-degree of 3 dB hybrid circuit is connected at the output of each source. This circuit distributes the power equally and with a 90-degree, aperiodic phase shift, towards two equipotential distributors in equiphase, with m inputs and n outputs, having one and the same input/output phase shift. The two distributors are connected, respectively, to the two ports of a pair of conjugated ports of n 90-degree 3 dB hybrid circuits. The powers recombined in these n circuits are respectively delivered to n users.
