The structure of impedance matching network and the essence of tuning algorithm in antenna tuner are introduced,and the heuristic algorithm called neighbor searching algorithm is proposed to solve the NP-hard problem. Then the iteration steps of nearest neighbor searching algorithm with fixed step size is described in detail which are applied to antenna tuner,and the algorithm is improved by different neighbor structures and searching patterns,so the searching space is reduced and the tuning speed is accelerated. At last four tuning algorithms based on nearest neighbor searching are simulated with a 10 m HF whip antenna and the validity of the improved algorithm is certified.
