Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. An electronic device, comprising:
a controller; and
an antenna apparatus, wherein the antenna apparatus is electrically connected with the controller;
wherein the antenna apparatus comprises:
an antenna module configured to receive and emit a radio frequency (RF) signal of a preset frequency band toward a preset direction range;
an antenna radome, spaced apart from the antenna module, located within the preset direction range, and comprising a substrate and a resonant structure carried on the substrate;
wherein the substrate is configured to allow a RF signal of a first frequency band in the preset frequency band to pass through, the resonant structure is configured to adjust a passband width of the substrate to the RF signal of the preset frequency band, to make the antenna radome allow a RF signal of a second frequency band in the preset frequency band to pass through, wherein a bandwidth of the second frequency band is greater than a bandwidth of the first frequency band, and the RF signal of the second frequency band comprises the RF signal of the first frequency band;
wherein the antenna module in the antenna apparatus is configured to receive and emit the RF signal through the antenna radome in the antenna apparatus under control of the controller; and
wherein the substrate at least comprises a battery cover, the battery cover is located within the preset direction range of the RF signal of the preset frequency band received and emitted by the antenna module, and the resonant structure is located on a side of the battery cover facing the antenna module.
