We use the concept of active antenna available power to derive a generalization of the Friis transmission formula for multiport antenna systems. With beamformer weights chosen such that the array patterns are the same when transmitting and receiving,

We investigate a reciprocal and passive linear time-invariant multiport, having a port set coupled to a generator and a port set coupled to a load, in the harmonic steady state. Two configurations are considered, in which the port set at which the ge

We investigate a passive linear time-invariant 2-port, having a port coupled to a generator and a port coupled to a load, in the harmonic steady state. Two configurations are considered, in which the port at which the generator is connected and the p

We derive some general properties of generalized Rayleigh ratios, and use these properties to present a detailed theory of two efficiency metrics relevant to a specified excitation of a multiport antenna array (MAA) by a linear time-invariant (LTI) m

International audience; We investigate the transfer of power between two passive linear time-invariant multiports having the same number of ports, in the harmonic steady state. One of the multiports is a generator in a configuration A, or a load in a

International audience; We identify five types of antenna tuner control scheme, which are suitable for a wireless transmitter using a single antenna. Four of them use a sensing unit measuring electrical variables either at the radio port or at the an
