Title:
RADIO WAVE MEASUREMENT SYSTEM AND WIRELESS POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/220996
Kind Code:
A1
Abstract:
When measuring antenna radiation patterns in an environment in which radio waves are reflected, it is difficult to measure with high precision due to the multipath effect. This radio wave measurement system is provided with: a flying body 3 that either moves or hovers in the air above a measured antenna 30 radiating a radio wave 2 toward the sky; and a position measurement unit 18 that measures the position of the flying body. A measurement antenna 14 for receiving the radio wave 2 and a radio wave measurement unit 15 for measuring received radio wave data 73 including at least one of the amplitude and the phase of the radio wave 2 received by the measurement antenna 14 are mounted on the flying body 3. The radio wave measurement system is additionally provided with a radiated radio wave data generation unit 21 for generating radiated radio wave data 71 including received radio wave data 73 and radio wave source relative position data 78 in which measurement point data 74 that is the position of the flying body 3 at the time the received radio wave data 73 was measured is represented as a position relative to the measured antenna 30.
