摘要

随着无线技术的加速发展,由于物联网(IoT)设备的需求不断增长,小型化天线受到了极大的青睐,这些设备对于适应低功耗、高数据速率和远程通信至关重要。当天线在较低频率下工作时,天线的尺寸变得笨重,由于其尺寸限制,这在物联网设备内的天线集成中提出了一个问题。为此,本文设计了一种基于矩形互补裂环谐振器(RCSRR)和开槽接平面的小型化环形单极天线,其工作频率分别为2.4 GHz和5.8 GHz。该天线小型化46.8%,整体尺寸为30 mm × 24.8 mm × 1.6 mm,印刷在介电常数为4.3的FR-4衬底上。通过修改天线结构、优化尺寸,采用介电常数为2.2、厚度为1.575 mm的低损耗Rogers RT5880衬底进行设计优化。天线宽度也减小到20mm,进一步减小了57.8%的尺寸。仿真结果表明,天线工作在2.448 GHz、2.864 GHz和5.8 GHz频段,回波损耗分别为-13.872 dB、-33.491 dB和-19.3 dB。采用不同的基片,对天线的制作和测量进行了最佳的仿真设计,并将仿真结果与实测结果进行了比较,验证了其性能。摘要/ abstract摘要:Dengan perkembangan pesat technology wayar,天线微型通信技术menjadi sangat digemari kerana permintaan and semakin meningkat bagi peranet Internet bada (IoT),无线通信技术(mempunyai kuasa rendah),数据通信技术(data) yang tinggi and berkomunikasi jarak jauh。Apabila天线beroperasi pada frekuensi rendah, saiz天线menjadi besar, ini menimbulkan isu kekangan saiz天线ketika berada dalam peranti IoT。谐振器Gelang Pemisah Pelengkap Segiempat Tepat (RCSRR) dan tanah berslot, telah direka bentuk pa jalur frekuens2.4 GHz和5.8 GHz。天线天线直径为30 mm × 24.8 mm × 1.6 mm,天线天线基材FR-4直径为4.3 mm。Reka bentuk最优telah dilakukan dengan mengubah suai结构天线,berdimensi最优,menggunakan基片Rogers RT5880 renah kuasa dengan pemaldielektrik 2.2, dan berketebalan 1.575 mm。Lebar天线juga dikurangkan sebanyak 20毫米,ini bermakna pengurangan saiz berjaya ditingkatkan kepada 57.8%。datatan模拟menunjukkan天线,在2.448 GHz, 2.864 GHz和5.8 GHz频率下,dengan pengurangan kehilangan pulangan kuasa yang baik iitu天线,-13.872 dB, -33.491 dB和-19.3 dB。Fabrikasi danpengukuran antena juga telah dilaksanakan padreka bentuk模拟terbaik menggunakan基质yang berbeza bagi mengesahkan kemampuannya dengan membandingkan dapatan模拟dengan hasil yang diukur。

Design of Miniaturized Antenna for IoT Applications Using Metamaterial
With the accelerated development of wireless technology, miniaturized antennae have become outstandingly favored due to the growing demand of Internet of Things (IoT) devices that are essential to accommodate low power, high data rates, and long-range communication. When an antenna operates at lower frequencies, the size of the antenna becomes bulky, which has raised an issue in the integration of the antennae within IoT devices due to their size constraints. Hence, in this paper, a miniaturized ring-monopole antenna incorporated with Rectangular Complementary Split Ring Resonator (RCSRR) and slotted ground plane, was designed at 2.4 GHz and 5.8 GHz frequency bands. The antenna was miniaturized by 46.8 % with overall size of 30 mm x 24.8 mm x 1.6 mm, and it was printed on FR-4 substrate with dielectric constant of 4.3. Design optimization was carried out by modifying the antenna structure, optimizing the dimensions, and using a low loss Rogers RT5880 substrate with a dielectric constant of 2.2, and thickness of 1.575 mm. The width of the antenna was also reduced to 20 mm which furthered the size reduction to 57.8 %. From the simulation results, the antenna was operated at 2.448 GHz, 2.864 GHz, and 5.8 GHz frequency bands with good return loss at -13.872 dB, -33.491 dB, and -19.3 dB respectively. The antenna fabrication and measurement were also implemented to the best simulated design using different substrates to validate its performance by comparing the simulated results with the measured results.
