ELECTRONIC DEVICE Russian patent published in 2023 - IPC H01Q1/22 H01Q1/44 

FIELD: electronic devices.

SUBSTANCE: implementation options of this application disclose an electronic communication device, including the first part and the second part. The first part and the second part can be folded relative to each other to a closed state and can be unfolded relative to each other to an open state. When the first part and the second part are in a closed state, the frame of the first part and the frame of the second part partially or completely overlap. The first part includes the first powered antenna, the first power circuit and the first grounding circuit, the first power circuit is connected to the first powered antenna and is capable of powering the first powered antenna, and the first grounding circuit is connected to the first powered antenna and is capable of grounding the first powered antenna. The second part includes the first passive antenna, and when the first part and the second part are in the closed state, the first passive antenna is not grounded and can have a connection with the first powered antenna to generate the first excited resonant signal by excitation.

EFFECT: formation of an additional resonant mode by means of the radiation frequency band on the first passive antenna, the expansion of the radiation bandwidth and ensuring relatively high efficiency of the antenna in the closed state.
