Abstract 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.

And Control

In this paper, a novel and compact center-fed dual-band WiFi printed antenna is presented. This antenna is designed using two different arms which correspond to the oscillation points of the dual band, and uses parasitic capacitance and U-shaped microstrip line to match and control the necessary bandwidth. The measured frequency bandwidth of this antenna is 2.3–2.61 GHz (310 MHz, 12.7%) at 2 GHz, and the high-frequency bandwidth is 4.82–5.84 GHz (1020 MHz, 19.1%) at 5 GHz, which meets the requirements for applications in global WiFi communication. This PCB antenna is double-sided, long, and narrow; its size is 7 × 45.9 × 1 mm3; it can be applied to wireless access point; and it has a near-omni-directional radiation pattern. The design, analysis, and measured results of this proposed antenna will be presented.

Antenna Structure

In this article, a dual-band notched ultra-wideband (UWB) dielectric resonator antenna is proposed. The antenna structure consists of Crescent Moon Dielectric Resonator (CMDR) fed by a stepped microstrip monopole printed antenna, partial ground plane, and an I-shaped stub. The Crescent Moon dielectric resonator is placed on the microstrip monopole printed antenna to achieve wide impedance bandwidth, and the I-shaped stub is utilized to improve impedance bandwidth for the WiMAX band. A comprehensive parametric study is carried out using HFSS software to achieve the optimum antenna performance and optimize the bandwidth of the proposed antenna. The entire band is useful with two filtered bands at 5.5 GHz and 6.8 GHz by the creation of notches. The band’s rejection, WLAN band (5.2–5.7 GHz), and the downlink frequency band of ITU 7 GHz-band for satellite communication (6.5–7.3 GHz) is realized by inserting G-shaped and C-shaped slots in the ground. The simulation results demonstrate that the proposed CMDR antenna achieves satisfactory UWB performance, with an impedance bandwidth of around 88.7%, covers the frequency band of 3.2 - 8.3 GHz, excluding a rejection band for the WLAN and ITU 7 GHz band. The CMDR is simulated using HFSS and CST high-frequency simulators.
