在这封信中，提出了一种采用高阶腔模式，即TE440模式的单馈低轮廓高增益圆极化开槽腔天线。所提出的天线结构简单，由辐射线极化开槽腔天线和线圆极化变换器组成。以低成本标准印刷电路板（PCB）工艺制作的WLAN 5.8 ghz频段天线原型为例验证了所提出的概念。给出了实测结果与仿真结果的比较，仿真结果与实测结果吻合较好。
In this letter, a single-fed low-profile high-gain circularly polarized slotted cavity antenna using a high-order cavity mode, i.e., TE440 mode, is proposed. The proposed antenna has a simple structure that consists of a radiating linearly polarized slotted cavity antenna and a linear-to-circular polarization converter. An antenna prototype operating at WLAN 5.8-GHz band fabricated with low-cost standard printed circuit board (PCB) process is exemplified to validate the proposed concept. Measured results compared to their simulated counterparts are presented, and a good agreement between simulation and measurement is obtained.
