Sharp has constructed a state-of-the-art anechoic chamber in Japan to measure the efficiency of flat panel antennas for LEO and MEO satellites. Utilizing the Compact Antenna Take a look at Vary (CATR) technique, the chamber simulates long-distance communication situations, resembling these encountered in satellite tv for pc communication, over a brief bodily distance. Additionally it is able to accommodating one among Japan’s largest antennas, with an aperture of as much as 80 cm.
Designed with high-quality radio wave-absorbing supplies on the ceiling, partitions, and flooring, and geared up with parabolic reflectors, the chamber suppresses undesirable reflections and measures efficiency over a brief distance. Whereas typical chambers require over 60 meters to check an 80-cm aperture antenna, Sharp’s CATR-based setup achieves correct measurements over roughly 7 meters throughout a frequency vary of 10 GHz to 40 GHz.
Along with supporting Ku/Ka bands used for satellite tv for pc communications, the anechoic chamber additionally accommodates measurements within the higher mid-band (FR3 6 GHz to 24 GHz), a possible frequency vary for 6G deployment. The brand new chamber facility, launching this month, will allow testing and technical verification of assorted merchandise, together with next-generation smartphones.
