Abstract: A four-notch flexible wearable ultra-wideband antenna fed by coplanar waveguide, includes a flexible base. A ground plane, a radiation patch and a feeder are arranged on the flexible base. There are several resonant tanks on the feeder and the radiation patch. The flexible base is made of insulating flexible material, and the feeder, the radiation patch and the ground plane are made of conductive flexible material. The four-notch flexible wearable ultra-wideband antenna fed by coplanar waveguide of the present application can be prepared by layer-by-layer assembly technology, spray printing or printed circuit board technology, and has the advantages of miniaturization and low profile, compact structure, convenient production, good conformality, wearable and other advantages.

Abstract: A method for acquiring a battery capacity, includes: acquiring multiple initial charging parameters of a battery when the battery is charged during a current charging process, where state of charge (SOC) of the battery in the current charging process changes for a range covering an SOC range, or a minimum charging temperature of the battery in the current charging process is greater than or equal to a temperature threshold; periodically acquiring multiple actual charging parameters of the battery during the current charging process and a current number of charging times corresponding to the current charging process; and acquiring, according to the multiple initial charging parameters, the multiple actual charging parameters, and the current number of charging times, a predicted battery capacity of the battery in a next charging process.
