Abstract

A method improves antenna matching for a node, in particular a sensor apparatus and/or actuator apparatus, of a communications network. The node is capable of radio communication and has a radio module equipped with an antenna and a transmit path and/or receive path for radio signals to be emitted and/or received. The node has a power supply apparatus, which is preferably energy self-sufficient, in particular a battery. The antenna has an impedance and in the receive situation and/or in the transmit situation in the case of adjustable matchings, preferably by use of adjustable matching networks, the signal to noise ratio associated with each matching is estimated, and a matching is selected from the different matchings for the receive mode and/or the transmit mode.
