Abstract (in Japanese) (See Japanese page) 
(in English) Beyond 5G/6G mobile communications aims to expand coverage and increase communication speed and capacity by utilizing HAPS (High Altitude Platforms System), and Massive MIMO using multiple antenna elements is being considered for base station equipment. The authors have proposed a simultaneous multi-beam base station using a staircase array antenna with multiple boards stacked in a stepped pattern, a Butler matrix circuit, a variable phase shifter, and an amplifier. Since the amplifiers are arranged in a stepped pattern that is different from the conventional method, the heat dissipation characteristics have not been considered much. In this report, we report the results of a thermal fluid simulation of the heat dissipation characteristics when an amplifier IC is mounted on the board of an X-band 64-element staircase array antenna. We also report the impact of adding a cooling fan on the wireless beam pattern, which was evaluated using an electromagnetic field simulation.
