無線通信電力伝送のための受信受電用5．8GHzレクテナアレー

摘要

By recent progress on semiconductor devices, high power and low consumption communication systems can be realized. Due to diis progress, it becomes possible to utilize the carrier energy as well as to convey the information effectively. For this purpose, the transmitter system was made with high performance such as the beam steering, and the receiver system must be realized with the small size and multi-functions of extraction of the carrier energy and of demodulation of the information out of the electromagnetic wave sent from the transmitter. In this study, a 5.8 GHz receiving and rectenna array has been developed for the small and high performed active integrated antenna in the small-sized transmitter/receiver and power-transfer / rectenna system. The module studied here has the functions of converting the carrier energy to the DC power as well as of demodulating the propagating signal. Under this concept, the rectenna array consisting of a small antenna and a detector was made.%近年の半導体デバイスの発展により、電子通信機器では高出力化や低消費電力化が進み、情報を取り出すことと同時に、キャリアの電力も有効利用することが可能となってきた。このためには、送信側では電子ビーム操作機能を持たせて高性能化し、送られてきたマイクロ波のキャリアを低周波に変換して電力を取り出し、かつ、情報を復調させる小型の受信・受電回路が必要となる。そこで本研究では、動作周波数5．8GHzにおける小型高性能アクティブ集積アンテナのうち、受信受電系に着目して開発を行った。マイクロ波を直流に変換する整流回路（Rectifier）に情報を取り出す機能を追加し、アンテナ（Antenna）と整流回路を一体化したレクテナ（Recternna）を作製して、受信・受電の高効率化を行った。
