Dynamic real-time calibration for antenna matching in a radio frequency receiver system

A network server comprising a computer recordable storage medium tangibly embodying computer executable program code, which when executed by a controller, performs actions comprising:

• solving, with a non-linear optimizer, for a reflection coefficient of an antenna by calculating a solution to two non-linear equations;
• converting, through the controller, the reflection coefficient to a value of an input impedance of the antenna;
• and
• tuning a number of reactive elements of a matching network to values that match the input impedance.

A computer implemented method of matching the impedance of an antenna, the computer implemented method comprising:

• solving with a non-linear optimizer, for a reflection coefficient of an antenna, ΓA, by calculating simultaneously a solution to two non-linear equations;
• converting, through a controller, the reflection coefficient to a value of an input impedance of the antenna;
• and
• tuning a number of reactive elements of a matching network to values that match the input impedance.
