[0044] Antennas are the main components of electronic devices to achieve wireless communication. As described in the background technology, in existing electronic devices, antennas are generally set on the circuit board. Antennas of different communication standards need to have certain size requirements. With the diversification of wireless communication functions of electronic devices, electronic devices need to support multiple different communication standards, and multiple antennas need to be set. The lightweight design of electronic devices is the development trend of electronic devices, and there is not enough space on the circuit board to arrange antennas.
