Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An antenna apparatus, comprising:
an antenna module configured to receive and emit a radio frequency (RF) signal of a preset frequency band toward a preset direction range; and
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 resonant structure comprises a first resonant layer and a second resonant layer that are stacked, the first resonant layer is farther away from the antenna module than the second resonant layer, a resonant frequency of the first resonant layer is a first frequency, a resonant frequency of the second resonant layer is a second frequency, and the first frequency is greater than the second frequency.
