技術說明

本計畫承襲主動式電子掃描陣列天線的設計理念，以注入鎖定振盪器為基礎，配合饋入網路以及圓極化天線，完成主動天線單元設計。將天線單元的饋入網路相連接後，可組合成陣列天線。此架構不僅可以利用自我注入鎖定機制而對環境中的振動有優異的靈敏度，且可透過交互注入鎖定機制改變天線單元間的相位差，而具有波束成形的能力。當多位靜止受測者處於彼此肩並肩、與天線間的距離及方位角皆不同、或在遮蔽物後的情形下，同時感測其生理徵象與方位角資訊，可滿足在醫療照顧、智慧家電、與居家安全防護應用的實際需求。 This project follows the design of active electronically scanned array, based on injection-locked oscillators with feeding network and circular-polarization antennas for completing the active antenna. An antenna array can be formed by feeding the antenna units into the network. This architecture has high sensitivity toward vibration in the environment because of its self-injection locking mechanism and has beamforming capability through the mutual injection locking mechanism that changes the phase difference between antenna units. The testing will involve stationary subjects placed shoulder to shoulder, at different distances and azimuths relative to the antennas, and placed behind obstructions, while vital signs and azimuth information is being detected, which will serve as reference for applications in areas including medicine, smart appliances, and home security.
