Abstract: A switching method for multiple antenna arrays is disclosed which including: turning on a number of antenna arrays of an electronic device, and obtaining multiple received powers of a beam signal; turning off the antenna array(s) other than the antenna array having the largest received power, and calculating multiple first power ratio parameters according to the received powers; calculating a first channel information of the antenna array which is turned on; calculating a first virtual channel information of each of the antenna arrays which are turned off according to the first channel information, the first power ratio parameter corresponding to each of the antenna arrays which are turned off and an angle mapping table; and selecting one of the antenna arrays to turn on according to the first channel information and all the first virtual channel information, and turning off the rest antenna array(s).
