A method and system for reducing switching delay of multi-band antennas

Abstract

This invention relates to the field of communication antenna technology, and discloses a method and system for reducing switching delay of multi-band antennas. The method includes: monitoring the reflected signal of the antenna in a real-time frequency band to obtain radiation performance data, and determining candidate operating frequency bands based on the radiation performance data and the structural characteristics of the antenna; adjusting the impedance of the candidate operating frequency bands to obtain an optimized path frequency band; analyzing the signal reflection response of the optimized path frequency band to obtain the impedance parameters before optimal matching; comparing the impedance parameters before matching with a historical performance database, and mapping the optimized path frequency band to target parameters based on the comparison results to obtain target matching parameters; judging the compliance of the radiation performance data and target matching parameters with switching conditions to obtain a frequency band switching command; monitoring the response to the frequency band switching command, and inputting the monitored data into the historical performance database. This invention can improve the efficiency of reducing switching delay of multi-band antennas.
