Antenna parts play a critical role in 5G networks, the next generation of wireless communication. With the higher frequency bands used in 5G, antenna design and performance become even more crucial. Millimeter-wave antennas, phased array antennas, and beamforming techniques are employed to achieve the required data rates and coverage in 5G networks. These antenna parts enable the transmission of high-frequency signals and facilitate the implementation of advanced 5G features like massive MIMO and dynamic beamforming.
