Abstract

The paper presents a probe fed slotted hexagonal patch antenna and emphasizes on antenna performance after suppression of a spurious radiation. To suppress the spurious radiation two complementary split ring resonators (CSRRs) are inserted in the reduced ground plane. Based on simulated antenna performance characteristics such as reflection coefficient, impedance and far field radiation pattern of the CSRRs embedded antenna have been analyzed and compared with the antenna without CSRRs. Equivalent circuit model of the antenna with CSRRs has been incorporated to explain the effect of CSRRs on antenna scattering and impedance performance. Due to the suppression of dual resonance in the antenna with CSRRs, narrower bandwidth (∼ 220 MHz) is observed along with reduced backside radiation in the antenna with CSRRs when compared with the antenna without CSRR. The proposed antenna can be utilized in diverse applications within (U-NII-2C) WLAN band.

利用互补裂环谐振器抑制开槽六边形天线中的杂散辐射

提出了一种探头馈电的开槽六边形贴片天线，重点研究了天线在抑制杂散辐射后的性能。为了抑制杂散辐射，在减少的地平面中插入两个互补的裂环谐振器。在模拟天线性能的基础上，分析了csrs嵌入式天线的反射系数、阻抗和远场辐射方向图等特性，并与无csrs的天线进行了比较。采用等效电路模型对天线的散射和阻抗性能进行了分析。由于在有CSRR的天线中抑制了双共振，与没有CSRR的天线相比，有CSRR的天线中观察到更窄的带宽(~ 220 MHz)以及减少的背面辐射。该天线可用于(u - ni - 2c) WLAN频段内的各种应用。
