An antenna component is provided. An orthographic projection of auxiliary antennas on a 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, so that a signal emitted from the radiation-sensitive area where the SAR value of the frequency band needs to be reduced on a primary antenna may be absorbed by the auxiliary antennas, and the auxiliary antennas generate secondary radiation.

Antenna component and communication device

An antenna structure, PCB and mobile terminal for Sub-6G. The antenna structure includes a first branch and a second branch. The first branch includes an L-shaped arm and a first longitudinal arm extending outwardly from the PCB. The first longitudinal arm is connected to the ground of the PCB. One end of the L-shaped arm is connected to the end of the first longitudinal arm. The second branch is L-shaped, and one end of the second branch is connected to the antenna feed point of the PCB. At least one microstrip line is connected between the first longitudinal arm and the second branch.
