Abstract
An antenna including an array of N-port receive antennas; an array of M-port transmit antennas; and a plurality of cells for coupling the receive antennas to the transmit antennas, each cell having plural amplifiers coupled between the receive antenna and the transmit antenna thereof. The amplifiers may be replaced with injection-locked oscillators. In the best mode, an arrangement is included for distributing signals between the ports of the receive antenna and the amplifiers and between the amplifiers and the transmit antenna. This arrangement may be a manifold such as a network of power combiners and dividers.
