摘 要：提出一种同时面向全球定位系统（GPS）和无线局域网（WLAN）应用的双频带蝶形微带天线。该天线由两对尺寸不同的蝶形贴片构成，两对贴片谐振在不同的频率，从而形成相互独立的双频特性。通过商业仿真软件 HFSS13.0 对该双频蝶形微带天线进行仿真优化分析，结果表明，文章设计的双频带蝶形天线拥有良好的 10 dB 阻抗匹配带宽（第一通带为 670 MHz；第二通带为 1 130 MHz），可以有效覆盖 GPS 和 WLAN 的频带应用。

Abstract: A dual-band bow-tie microstrip antenna for the Global Positioning System (GPS) and Wireless Local Area Network (WLAN) applications is proposed. The antenna is composed of two pairs of bow-tie patches with different sizes. The two pairs of patches resonate at different frequencies to form independent dual frequency characteristics. This paper carries out the simulation and parameter optimization for the dual-band bow-tie microstrip antenna by High Frequency Structure Simulator (HFSS, ver 13.0). The results show that the dual-band bow-tie antenna designed by this paper has a good 10 dB impedance matching bandwidth (the first passband is 670 MHz, the second passband is 1 130 MHz), which can effectively cover the GPS and WLAN band applications.
