High-gain concealed antenna circuit and structure of product with external power supply lead

According to the high-gain concealed antenna circuit and structure suitable for the product with the external power supply lead, on one hand, an antenna oscillator with the length of the antenna oscillator prolonged is designed by enabling an external power line to penetrate through a coupling antenna coil or enabling a wire connected with the external power supply line to penetrate through the coupling antenna coil; on the other hand, the'coupled antenna coil 'is coupled with the power supply line, and the originally needed'antenna' is moved to any place with the power supply line, so that the'coupled antenna coil 'can be conveniently designed at any place with the power supply line, especially in a shell or a disguised shell. And on the other hand, the other designed antenna oscillator is a shell oscillator, large-area conductors such as a metal shell, a shielding layer and a heat dissipation layer are fully utilized, the effective area of the other oscillator of the antenna is enlarged, the gain of the ant
