The invention provides an indoor ultra-wideband transparent directional antenna, which comprises a transparent outer cover, a transparent bottom plate, a base, a first rhombus array and a second rhombus array, and is characterized in that each of the first rhombus array and the second rhombus array comprises four transparent oscillators, and the four transparent oscillators are arranged in a rhombus shape; the first rhombus array is connected with the first feed network, and the second rhombus array is connected with the second feed network. The diamond array can maximize the diagonal distance between the units, which is crucial for suppressing the grating lobes of the antenna, especially for suppressing the grating lobes at the high-frequency end. And the grating lobes can cause energy to radiate towards unwanted directions, so that the gain and efficiency of the antenna are reduced. The four transparent oscillator diamond arrays achieve good balance among performance, flexibility, complexity and cost.

This application discloses a power supply control method, device, medium, and vehicle for a hybrid supercapacitor system. Upon receiving a vehicle start command, the method acquires the real-time temperature and real-time state of charge of the hybrid supercapacitor component. If the real-time temperature is determined to be below a self-heating trigger temperature threshold, the method controls the component to output a starting current to the vehicle start component. This starting current flows through an internal resistor, generating Joule heat and thus raising the component temperature. After the start-up process is completed, the method dynamically adjusts the output current and output voltage parameters of the power conversion component based on the real-time temperature and state of charge to control the component's real-time temperature within a preset operating temperature range. This application utilizes the start-up process to achieve synchronous self-heating, eliminating the need for additional heating hardware and preheating waiting time. Furthermore, dynamic reheating after start-up effectively maintains a suitable operating temperature, improves vehicle start-up delay, and significantly enhances the reliability of the system's low-temperature power supply.
