Abstract >In this paper, a circularly polarized (CP) planar antenna covering global positioning system (GPS) L1 (1575.42?MHz), L2 (1227.6 MHz), and L5 (1176.45?MHz) bands is presented. The antenna consists of an elliptical patch excited through the inset feed line. A pair of concentric ring slots is etched on the ground plane to achieve dual‐band response that covers L5/L2 and L1 bands. The circular polarization is achieved by integrating a quarter‐wavelength arc with the inset feed and loading a pair of slits on the elliptical patch. In addition, the quarter‐wavelength arc improves the impedance bandwidth of the lower resonant band to cover the GPS L5 band. The antenna shows right‐hand circular polarization (RHCP) in all the three bands. The antenna also satisfies the ±1 dBi gain flatness criteria of the GPS antenna. A prototype antenna is fabricated and experimental results are found in a good match with the simulated results. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display:

title> 在本文中，提出了一种覆盖全球定位系统（GPS）L1（1575.42〜MHz），L2（1227.6MHz）和L5（1176.45·4MHz）带的圆极化（CP）平面天线。天线包括通过插入馈电线激发的椭圆形贴片。在接地平面上蚀刻一对同心环槽以实现覆盖L5 / L2和L1带的双频带响应。通过将四分之一波长电弧与插入件馈送相积分并在椭圆形贴片上装载一对狭缝来实现圆极化。另外，四分之一波长电弧改善了下谐振带的阻抗带宽以覆盖GPS L5频带。天线在所有三个带中显示右侧圆形极化（RHCP）。天线还满足GPS天线的±1 dBi增益平坦度标准。原型天线是制造的，并且在与模拟结果的良好匹配中发现实验结果。</ p> </摘要> </span> <span
