“…In this paper, we develop an 8 × 8 photonic array antenna for 40-GHz band with integrated PDs and RF chains, and conduct end-to-end downlink transmission experiments including 20-km A-RoF link and 3-m over-the-air link using 3GPP-compriant 64-QAM OFDM radio signals, for the first time. It has been confirmed that 40-GHz RF signal after end-to-end transmission satisfies the criteria of 3GPP signal quality requirements within ±50 degrees of main beam direction [29]. We also evaluate the power fading effect of the RF signal after A-RoF transmission, which is caused by chromatic dispersion of the single mode fiber (SMF).…”

In 5th generation (5G) and Beyond 5G mobile communication systems, it is expected that numerous antennas will be densely deployed to realize ultra-broadband communication and uniform coverage. However, as the number of antennas increases, total power consumption of all antennas will also increase, which leads to a negative impact on the environment and operating costs of telecommunication operators. Thus, it is necessary to simplify an antenna structure to suppress the power consumption of each antenna. On the other hand, as a way to realize ultra-broadband communication, millimeter waves will be utilized because they can transmit signals with a broader bandwidth than lower frequencies. However, since millimeter waves have a large propagation loss, a propagation distance is shorter than that of low frequencies. Therefore, in order to extend the propagation distance, it is necessary to increase an equivalent isotropic radiated power by beamforming with phased array antenna. In this paper, a phased antenna array module in combined with analog radio over fiber (A-RoF) technology for 40-GHz millimeter wave is developed and evaluated for the first time. An 8 × 8 phased array antenna for 40-GHz millimeter wave with integrated photodiodes and RF chains has been developed, and end-to-end transmission experiment including 20 km A-RoF transmission and 3-m over-the-air transmission from the developed phased array antenna has been conducted. The results showed that the 40-GHz RF signal after the end-to-end transmission satisfied the criteria of 3GPP signal quality requirements within ±50 degrees of main beam direction.
