Designing miniaturized multiband antennas to cover both the 5G new radio frequencies (FR1 and FR2) simultaneously is a challenge for wireless communication researchers. This paper presents two antenna designs : a dual-band printed antenna of size 18 × 16 × 0.285 mm3 operating at FR1–5.8 GHz and FR2–28 GHz and a triple-band printed antenna with dimensions 30 × 25 × 0.543 mm3 operating at FR1–3.5 GHz and 5.8 GHz (sub-6 GHz microwave frequency bands) and FR2–28 GHz (mm-wave frequency band). The final projected triple-band antenna has a compact size with an impedance bandwidth of 12.71%, 11.32%, and 18.3% at 3.5 GHz, 5.8 GHz, and 28 GHz, respectively with the corresponding gain of 1.86 dB, 2.55 dB, and 4.41 dB. The measured radiation characteristics of the fabricated prototypes show that the proposed designs are suitable for trendy 5G-RFID and mobile Internet of things (IoT) applications.

用于 5G-IOT 应用的紧凑型双频和三频天线

设计同时覆盖 5G 新无线电频率(FR1 和 FR2)的小型化多频带天线是无线通信研究人员面临的挑战。本文介绍了两种天线设计:尺寸为 18 × 16 × 0.285 mm 3的双频印刷天线,工作频率为 FR1-5.8 GHz 和 FR2-28 GHz,尺寸为 30 × 25 × 0.543 mm 3的三频印刷天线工作在 FR1–3.5 GHz 和 5.8 GHz(低于 6 GHz 的微波频段)和 FR2–28 GHz(毫米波频段)。最终投影的三频天线尺寸紧凑,在 3.5 GHz、5.8 GHz 和 28 GHz 下的阻抗带宽分别为 12.71%、11.32% 和 18.3%,相应的增益为 1.86 dB、2.55 dB 和 4.41 D b。所制造原型的测量辐射特性表明,所提出的设计适用于流行的 5G-RFID 和移动物联网 (IoT) 应用。
