چکیده
A wireless network using high altitude platforms located in the stratosphere is attracting interests as a new network infrastructure. This paper provides the design concept and basic performance of the prototype of onboard digital beamforming (DBF) antenna in Ka band, which achieves quick-response and robust space division multiple access (SDMA) schemes. The configuration of the prototype DBF antenna, beamforming algorithm, and pattern measurement results obtained by offline beamforming in an anechoic chamber are shown.
