摘　　要：声表面波(SAW)无源无线传感器常用于检测复杂环境下的物理参数。针对SAW无线无源传感器天线对低轮廓、小尺寸天线的要求,同时采用短路加载技术和贴片开槽技术,设计了一款小型化的低轮廓微带天线,天线贴片尺寸仅为21.4 mm×21.3 mm,高度仅1 mm。测试结果表明,天线,在小型化、低轮廓与增益之间取得良好折中。利用制作的天线,实现了SAW无源无线传感器的检测。Surface acoustic wave （ SAW ） passive wireless sensors are often used to sense physical quantity under complex environment. A novel miniaturized slotted Planar Inverted F Antenna（ PIFA） antenna is proposed to meet the requirements of low profile and small size for the surface acoustic wave（ SAW） passive wireless sensor. The size of the radiating element is 21. 4 mm by 21. 3 mm with the height of 1 mm. The measurement results show that the gain of the fabricated antenna is -7. 86 dB. According to the measurements,the antenna reached a good compromise between miniaturization and gain. The SAW passive wireless sensor is detected with the fabricated antenna.
