摘要

本文基于集总电路模型对典型的PCB分环谐振器(SRR)电小天线(ESA)进行了分析。由于技术上的限制，如5密尔的铜线宽度和3.5密尔的痕量分离，它本身就缺乏足够的阻力来有效地运行。通过一系列不同的SRR配置，可以改进这一点，使SRR ESA在更低的频率上共振。提出了一种四根六方双SRR (FSHD-SRR) ESA超谐振器的平面结构，可以充分覆盖WiFi 2.4 GHz频段。然后，在从通道1 (2.412 GHz)到通道13 (2.472 GHz)的整个WiFi 2.4 GHz频率范围内对所提出的设计进行了仿真和制作，极端通道的反射系数S11小于−10 dB，中心通道7 (2.442 GHz)的反射系数S11小于−30 dB。

Design of 2.45 GHz ESA metaresonator

This paper shows the analysis of a typical Printed Circuit Board (PCB) Split Ring Resonator (SRR) Electrically Small Antenna (ESA) based on lumped circuit model. Having technical limitations such as 5 mils copper trace width and trace separation of 3.5 mils, it inherently lacks sufficient resistance to operate efficiently. Through a series of different SRR configurations, this can be improved to shift the SRR ESA to resonate at a lower frequency. A planar configuration of Four Stubs Hexagonal Double SRR (FSHD-SRR) ESA metaresonator is proposed to operate sufficiently to cover the WiFi 2.4 GHz band. Then, the proposed design is simulated and fabricated over the entire WiFi 2.4 GHz frequency range from channels 1 (2.412 GHz) to 13 (2.472 GHz) with a reflection coefficient, S11 of less than −10 dB for the extreme channels and −30 dB for the center channel 7 (2.442 GHz).
