Mobile Satellite Communication System High-Functioning Antenna

摘要

The National Institute of Information and Communications Technology (NICT) developed a highly functional active phased array antenna (APAA) for a land mobile vehicle as a part of the mobile satellite communications system experiment using ETS-Ⅷ satellite. The antenna is light weight, low profile and has a capability of automatic satellite tracking by using the electronic beam scanning. The effectiveness of the antenna was confirmed by the tests of basic performance, tracking performance and transmission performance by using the satellite signal.
