Antenna switching method and device and storage medium

The invention provides an antenna switching method and device and a storage medium, which are applied to a terminal, and the terminal comprises a plurality of antennas. The method comprises the following steps: when a terminal is in a non-connection state, determining that a detection condition is met; wherein the non-connection state comprises an idle state and/or an inactive state; when the detection condition is satisfied, controlling N antennas of the terminal to enter an on state; wherein N is greater than or equal to 2 and is less than or equal to a positive integer of a total antenna included in the terminal; after the N antennas enter the on state, reference signal measurement is carried out to obtain a signal measurement result; according to the signal measurement result, M antennas are selected to be maintained in an on state, and M is smaller than N. Therefore, when the terminal is in the non-connection state, the antenna with relatively good antenna performance can be selected to work, so that the
