Abstract (in Japanese) (See Japanese page) 
(in English) While the 5G is expected to be an important technology for regional development and solving regional issues, a key issue for the 5G Evolution and 6G era is expected to be expanding the communication area to any place where its benefi ts can be enjoyed.
To expand the communication area, we are focusing on implementing a communication area from the sky using satellites and High-Altitude Platform Station (HAPS).
In particular, for HAPS, which can park in fi xed locations at a lower altitude than satellites, the use of broadband millimeter-wave is expected to enable the timely provision of high-speed, large-capacity, low-latency lines required in any location including at sea, in the air, or remote areas.
Before using the actual HAPS system, we performed an initial experiment to measure the propagation of the 39 GHz band using a small aircraft.
Experimental results assuming HAPS in an urban area, a forest, and a remote island show propagation loss in the 39 GHz band in various environments under the influence of aircraft turning.
