ANTENNAE ARRAY COMPRISING THREE-PORT CIRCUITS

摘要

The invention relates to antennae systems wherein a plurality of individual antennae (A1 An) that are respectively embodied as multiport circuits (S1,S2; D1 Dn) are interconnected as antennae paths. Information on the complex structure of the incoming signal can be calculated from a combined evaluation of the respective reception data. According to the invention, three-port circuits (adders) are used for individual antennae. A common reference for phase-locked synchronisation is supplied to all available antennae paths by means of a local oscillator. In this way, the output data of the respective antenna paths is correlated with each other such that both the I/Q values of the receiving signals and the solid angles of the Poynting vector can be clearly defined.
