A compact T-complementary split-ring resonator (CSRR) antenna was developed. Different from traditional designs, the proposed CSRR functioned not only as a loading structure but also as a radiator. The operation of the T-CSRR antenna was similar to that of a slot antenna with a gain of 3.1 dBi. Because of the loading effect of the CSRR, the size of the radiator of the proposed antenna was only 0.14λ₀ × 0.26λ₀. The circuit sizes of the proposed T-CSRR antenna were 50% and 74% smaller than those of the traditional half-wavelength slot and T-shaped monopole antennas, respectively. For further gain enhancement, the performance of two feasible array arrangements, namely collinear and parallel arrays with 1 × 4 T-CSRR elements, were compared, which revealed that the parallel 1 × 4 T-CSRR antenna array can achieve a gain of 9 dBi at 2.45 GHz.

开发了一种紧凑型 T 型互补裂环谐振器 (CSRR) 天线。与传统设计不同，所提出的 CSRR 不仅用作负载结构，还用作散热器。T-CSRR 天线的操作类似于增益为 3.1 dBi 的缝隙天线。由于CSRR的负载效应，建议天线的辐射体尺寸仅为0.14 λ ₀  × 0.26 λ ₀. 所提出的 T-CSRR 天线的电路尺寸分别比传统的半波长缝隙和 T 形单极天线小 50% 和 74%。为了进一步增强增益，比较了两种可行的阵列布置，即具有 1 × 4 T-CSRR 元件的共线阵列和平行阵列的性能，结果表明平行 1 × 4 T-CSRR 天线阵列可以实现 9 dBi 的增益在 2.45 GHz。
