The Complementary Split-Ring Resonator (CSRR)-loaded crescent slot circular antenna is presented in this paper. The proposed antenna is resonating at 2.4GHz with the gain of 2.38dB. The antenna is designed for a predefined shape, which has a crescent slot, star-shaped small slots and spline split on a circle. The CSRR is carved on the ground surface of the antenna to acquire 2.4GHz and eliminates the multiple resonances created by various slots. The CSRR provides the miniaturization by shifting the resonance from 2.59GHz to 2.4GHz. The measured, −6dB impedance bandwidth of the antenna is 11.25%. The antenna is fabricated using an FR4 (εr=4.4) substrate. The proposed crescent slot circular antenna is simulated using Ansys HFSS 17.0.

用于 WLAN/Wi-Fi 应用的加载 CSRR 的新月槽圆形天线

本文介绍了加载互补裂环谐振器（CSRR）的新月形槽圆形天线。建议的天线谐振在 2.4GHz，增益为 2.38D b。天线设计为预定义的形状，具有月牙形槽、星形小槽和圆形上的花键分割。CSRR 刻在天线的地表上以获得 2.4GHz 并消除了由各种插槽产生的多重共振。CSRR 通过将共振从 2.59 偏移来实现小型化GHz 至 2.4千兆赫。测得，-6天线的dB阻抗带宽为11.25%。天线是使用 FR4 (εr=4.4） 基质。使用 Ansys HFSS 17.0 对建议的新月形槽圆形天线进行仿真。
