FETを用いた2×2アクティブ集積アンテナおよびMMICを用いた超小型アクティブ集積アンテナアレイ

Millimeter wave frequencies are expected to be important for the high speed and large volume communication system in the multi-media society. Demands of light-weight, multi-functions are very high for such a system. The active integrated antenna is one of techniques to solve these problems. In this report, for use in the Intelligent Transport System (ITS), a 5.8GHz 2×2 active integrated antenna array fabricated on a soft substrate with a package-type FET and a K-band 2-element active integrated antenna array fabricated on a ceramic substrate with a MMIC oscillator were demonstrated. From the experimental results, it is believed that fundamental data for the new communication system were obtained.
