Antenna Array Design for Bluetooth Application

Bluetooth technology enables low energy short-distance data transfer which has revolutionized communication. Antennas are one of the most critical components of Bluetooth devices since they will affect the efficiency and the quality of the communication link. This review concentrates on the history and development of antenna arrays designed for Bluetooth applications. It describes classes of antenna arrays, design limitations for the 2.4 GHz ISM band, microstrip, PIFA, and beamforming array technologies. The paper describes issues related to miniaturization, interference, and power efficiency while also discussing integration with 5G, designs based on Artificial Intelligence, and wearable technology.
