| Summary: | 碩士 === 逢甲大學 === 通訊工程學系 === 105 === In this study, antennas for 5.8 GHz microwave motion sensor applications are investigated. The antennas are designed with considering the size and layout of the implementation area. For a long implementation area, such as a long corridor, a digifinger meander-line array antenna is designed with high gain and directional radiation pattern. For spacious implementation area, a backside slot patch antenna is designed with high gain and omni-directional radiation pattern. The proposed antennas improve the sensitivity of microwave motion sensors, which reduces the installation cost and enhances the practicability of the sensors. The proposed antennas implemented on FR4 substrate. The digifinger meander-line array antenna is designed at 5.8 GHz with 3.2 dBi maximum gain. The backside slot patch antenna is designed at 5.8 GHz with 4.5 dBi maximum gain. The proposed antennas are integrated with motion sensor to measure the microwave signal distribution in the implementation space. Finally, the distributions are compared with the radiation patterns of the proposed antenna.
