Abstract
A method includes, during transmission and/or reception of a radio frequency signal, detecting an impedance associated with an antenna connected with a matching network; algorithmically determining a reactance value of at least one reactive element that forms a part of the matching network in accordance with the detected impedance and at least one parameter including at least one of a currently used radio frequency, at least one user/device factor, at least one radio frequency offset value, and at least one predetermined constant; and setting the value of the at least one reactive element to match the determined value.

A method, comprising:
- during transmission and/or reception of a radio frequency signal, detecting an impedance associated with an antenna connected with a matching network;
- algorithmically determining a reactance value of at least one reactive element that comprises the matching network in accordance with the detected impedance and at least one parameter comprising at least one of a currently used radio frequency, at least one user/device factor, at least one radio frequency offset value, and at least one predetermined constant;
- and
- setting the value of the at least one reactive element to match the determined value.
An apparatus, comprising:
- a processor;
- and
- a memory including computer program code, where the memory and computer program code are configured to, with the processor, cause the apparatus at least to perform, during transmission and/or reception of a radio frequency signal,
- detecting an impedance associated with an antenna connected with a matching network;
- algorithmically determining a reactance value of at least one reactive element that comprises the matching network in accordance with the detected impedance and at least one parameter comprising at least one of a currently used radio frequency, at least one user/device factor, at least one radio frequency offset value, and at least one predetermined constant;
- and
- setting the value of the at least one reactive element to match the determined value.
