Abstract
An improved wireless radio-frequency (RF) transmission system is disclosed. The wireless RF transmission system comprises: 1) a radio frequency (RF) transceiver configured to transmit and receive radio-frequency signals; ii) an electrically small antenna having a complex impedance comprising a real part and an imaginary part; and iii) a tunable negative impedance converter (NIC) circuit coupling the electrically small antenna to the RF transceiver. The tunable NIC circuit is configured to perform antenna matching by reducing the imaginary part of the complex impedance of the electrically small antenna. The tunable NIC circuit is tuned by adjusting a transconductance value associated with the tunable NIC circuit.
