Electronic devices

Abstract

The invention proposes an electronic device. This electronic device comprises an antenna apparatus, which comprises multiple antenna units, and these antenna units are electrically connected to a grounding mechanism. When the grounding mechanism supplies power to these antenna units, the grounding mechanism carries a portion of the operating current. The transmission capacity is increased by using a grounding system. Between the antenna units positioned on the grounding system, a tight coupling is achieved, operation is performed in HWM (Half Wavelength Mode) and 0WM (One Wavelength Mode), and multiple operating frequency bands are created to meet communication requirements. Furthermore, because energy is transferred between antenna units using grounding, the currents of the antenna units are evenly distributed, and the SAR (Specific Absorption Rate) of the antenna units is low.
