ABSTRACT:
An apparatus, system and method optimize antenna performance using tunable parasitic elements by changing antenna characteristics based on signal quality parameters of electromagnetic signals exchanged through the antenna. The tunable parasitic elements are responsive to control signals to modify current flowing through a counterpoise of the antenna. Based on signal quality parameters received from a communication system, transmission characteristics are optimized by increasing the transmission gain in the direction of the receiving base station. Signal quality parameters measured at the antenna are used to change reception characteristics by minimizing reception gain in the direction of a jamming transmitter.
