System for matching impedence of antenna using greedy algorithm

摘要

The present invention relates to an antenna impedance matching circuit for outputting a plurality of antenna impedance values including a plurality of fixed impedances and a plurality of variable capacitors; An antenna impedance adjusting unit electrically connected to the antenna impedance matching circuit and adjusting the plurality of variable capacitors by comparing the plurality of fixed impedance values and the stored reference antenna impedance values to perform impedance matching of the antenna; And an antenna impedance matching circuit, wherein when the antenna impedance adjustment unit performs impedance matching of the antenna, coordinates are set based on the adjusted plurality of variable capacitors using a greedy algorithm, and impedance matching of the antenna is performed The value of the adjusted plurality of variable capacitors is set to a value in an area range of one of the reference variable capacitors in the range of the reference variable capacitor based on the predetermined ranges of the reference variable capacitors and the set coordinates And an antenna impedance matching system using a greedy algorithm including a radio frequency matching optimizer for varying antenna impedance matching.;
