Original Abstract Submitted
In electronic devices used in radio-frequency communications, impedance matching may result in desirable operating conditions. However, impedance of the antenna may change over time (e.g., due to frequency of signals being transmitted or received, due to ambient conditions, due to age of antenna or related components). Accordingly, it may be desirable to employ antenna tracking circuitry that may operate as an impedance matching network to dynamically match the antenna impedance. To dynamically match the antenna impedance, the matching network may include tunable components. To provide fast, dynamic, and effective impedance matching, antenna tracking circuitry having an architecture with analytically determinable impedance (e.g., determinable via one or more equations) may be implemented. The antenna tracking circuitry may include a variable resistor and three variable impedances. The three variable impedances may include components capable of tuning capacitor ranges of the three variable impedances, among other characteristics of the antenna tracking circuitry.
