In this paper, as one of the examples of an application of an active integrated antenna technique, a design method and experimental data of the active integrated amplifier antenna array were reported for microwave power transmission in the space solar power satellite 2000 system. The stacked structure of a unit cell in the array proposed here consists of three layers: the amplification circuit layer, radiation layer, and coupling layer. By incorporating 2×2 unit cells with the combination of a directional coupler and an FET amplifier, a light unit patch plate with weight of 200g.

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.

本報告では、MMIC発振器への光照射による周波数シフトについて実測及びシミュレータによる検証を行ったのでそれらについて報告する。発振器のゲートバイアスが浅い状態でのMMIC発振器への光照射では、発振周波数は高周波側にシフトした。また、マイクロ波回路シミュレーターを用いて、等価回路モデルの容量成分を変化させ、ハーモニックバランス解析を行った。容量成分cgdの増加が高周波側へのシフトに関係している計算結果を得た。
