AI Technical Summary
Technical Problem
Existing shark fin antennas use PCBs as radiators, resulting in high manufacturing costs and easy interference between radiators, which affects performance.
Method used
The design employs a multi-band shark fin antenna that does not use a PCB as the radiator. By combining multiple supports and antenna coils on the substrate, the isolation between the radiators is ensured, and the antenna coils and radiators are electrically connected to extend the electrical length.
Benefits of technology
This reduces manufacturing costs and effectively ensures isolation between radiators, thus improving antenna performance.
