This paper presents the design of fidget spinner-shaped antenna (FSSA) loaded with parasitic EC-SRR (edge coupled-split ring resonator) for multi-standard wireless applications. Parasitic EC-SRR element-loaded antenna helps to improve the impedance matching and bandwidth of antenna in comparison to the unloaded FSSA. The 50 Ω microstrip line fed has been applied to the structure of proposed antenna to obtain the distinct performance parameters such as reflection coefficient, gain, radiation pattern and efficiency. Comparison of the proposed antenna with and without SRR is made and found that the later case exhibits better results in terms of reflection coefficient and bandwidth. Bandwidth is increased by 21.61% at first two resonance points, 57.57% at third and 32.76% at fourth resonance point. A prototype of the proposed FSSA has also been fabricated and tested for validation of simulated results with measured results, and found in good agreement with each other. The overall dimensions of the proposed FSSA are 30 mm × 30 mm and can be used for different wireless applications in the frequency range 1.88–7.0 GHz, 7.81–8.85 GHz and 9.6–14.3 GHz.

本文介绍了用于多标准无线应用的，装有寄生EC-SRR（边缘耦合-分裂环形谐振器）的轻巧微调形天线（FSSA）的设计。与空载FSSA相比，寄生EC-SRR元件加载天线有助于改善天线的阻抗匹配和带宽。馈入的50Ω微带线已应用于拟议天线的结构，以获得独特的性能参数，例如反射系数，增益，辐射方向图和效率。对建议的带和不带SRR的天线进行了比较，发现后一种情况在反射系数和带宽方面表现出更好的结果。带宽在前两个共振点增加21.61％，在第三共振点增加57.57％，在第四共振点增加32.76％。还制造了拟议的FSSA原型，并对其进行了测试，以验证模拟结果与测量结果的一致性，并发现它们之间具有很好的一致性。拟议的FSSA的总体尺寸为30 mm×30 mm，可用于1.88–7.0 GHz，7.81–8.85 GHz和9.6–14.3 GHz频率范围内的不同无线应用。
