Classification: CPC H | IPC H

Claim 9:
10. 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 a difference between a reflection phase of the antenna radome to the RF signal of the preset frequency band and an incident phase of the antenna radome to the RF signal of the preset frequency band increases as a frequency of the RF signal increases, and the RF signal of the preset frequency band is allowed to pass through the antenna radome;
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.
