[0002] An antenna is an electronic device that converts electrical signals into electromagnetic waves and vice versa. Its core function is to transmit or receive electromagnetic waves in space. It is a key component of wireless communication, radar, navigation, and other systems. With the rapid development of terminal electronic products and the particularly rapid upgrading of smart devices, screen clearance is getting smaller and smaller, and mobile phone cameras are becoming more and more numerous. The increase in cameras reduces the clearance of antennas, makes the structural environment more complex, and leaves less and less area for antennas to run.
