The invention relates to an antenna structure, electronic equipment, an adjustment method, a storage medium and a program product. The antenna structure comprises a plurality of antennas which are arranged at intervals, and each antenna is connected with a corresponding signal circuit; the working frequency bands of the two adjacent antennas are staggered; and when one of the two adjacent antennas is in a working state, the circuit state of the signal circuit connected with the other antenna is adjusted, so that the two adjacent antennas can be electromagnetically coupled. According to the embodiment of the invention, the transceiving performance of the antenna is improved.

This invention provides a port status adjustment method, apparatus, computer-readable storage medium, and electronic device. The method includes: a first device acquiring a first message from a second device; the first device determining capability information of a first port based on first status information and the actual status of the first port read by the first device; and the first device activating the first port when the capability information matches the first capability information, thereby changing the state of the first port from an abnormal state to a normal state. This invention solves the problem of data loss caused by abnormal port states, thereby improving data interaction capabilities.
