Classification: CPC H | IPC H

Claim 7:
8. A communication device, wherein the communication device comprises an antenna component, and the antenna component comprises:
a circuit board, a primary antenna, and auxiliary antennas;
wherein a surface of the circuit board is provided with a circuit area and a clearance area, both the primary antenna and the auxiliary antennas are disposed corresponding to the clearance area, and the primary antenna is connected to the circuit area of the circuit board;
wherein the auxiliary antennas are neither connected to the primary antenna nor connected to the circuit area of the circuit board, an orthographic projection of the auxiliary antennas on the clearance area is entirely located in, partly located in, or close to a radiation-sensitive area where a specific absorption ratio (SAR) value of a frequency band needs to be reduced, and the auxiliary antennas are configured to receive a signal transmitted from the primary antenna and emit secondary radiation according to the signal;
wherein a number of the auxiliary antennas is at least two, and settings of a shape and the number of the auxiliary antennas satisfy that the SAR value of the antenna component that needs to be reduced is less than a target SAR value, and a total radiated power (TRP) loss caused thereby is less than a threshold value, and
wherein a distance between the primary antenna and one of the auxiliary antennas is less than ¼ of a wavelength of a signal within the frequency band of which the SAR value needs to be reduced, a length of the auxiliary antennas ranges from ½ to ⅕ of the wavelength of the signal within the frequency band of which the SAR value needs to be reduced, and the auxiliary antennas are all located between the primary antenna and the circuit area.
