| 摘 要： | 采用在贴片上开槽和加载的方法,设计了一种用于2.4GHz频段无线通信设备、内缩渐变线馈电的新型结构贴片天线.给出仿真设计的性能和多个天线样品的实测输入驻波比曲线和远区辐射特性图,详细研究分析了不同加载条件、不同辐射边尺寸对输入驻波比的影响.实测结果表明,该天线在2.4GHz频段上获得超过15%的相对带宽(VSWR<2),而且尺寸比相应频段的微带贴片天线更加微型化.

| Abstract: | By employing patch etching and loading techniques, a novel patch antenna fed by an inset taper line for 2.4GHz-band wireless communication equipments is designed in this paper. Simulation and measured data of VSWR and radiation pattern for the antennas with different dimension are given, and the effect of VSWR of different load and different dimension of radiation side are discussed in detail. Results show that the antenna has a bandwidth of over 15% centered at 2.4GHz (VSWR<2), and by employing loaded technique, more compact dimension than that of common microstrip patch antennas is achieved. |
