“…Table 1 presents a comparison of the proposed antenna with similar state-of-the-art works [12, 13, 17-19, 26, 27]. It can be seen that this design has a miniaturized size compared to the designs presented at [12,13,17,18,26,27], having the additional functionalities of structural conformability and frequency switching capability. Although the antenna reported in [19] offers the advantages of compact size, it has a setback of a rigid body which limits its usage in modern flexible devices.…”

“…Many 5G multi-band antennas have been reported in the literature. In [18], an efficient 5G antenna covering the frequency ranges from 3.45-3.8 GHz and 5-5.45 GHz is presented, while the provided response from [19] covers the LTE bands 42/43 and 46 ranging respectively from 3.4-3.8 GHz and 5.1-5.9 GHz. Similar work is presented in [20], which proposes a multiband printed planar Inverted-F antenna for 5G mobile handset.…”

A wide-band and tri-band flexible antenna for fifth-generation (5G) sub-6-GHz communication systems is investigated in this paper. The proposed wideband antenna covers the 5G new radio (NR) mid-band, ranging from 2.8 to 5.35 GHz, while the tri-band antenna is resonating at three different allocated frequency bands (2.45 GHz, 3.5 GHz, and 4.7 GHz) for 5G sub-6-GHz communications. This functionality is achieved by introducing hexagonal split-ring resonators in the radiating element, which can be controlled independently without affecting antenna performance to avoid problems of interference in this frequency spectrum. In addition, the antenna also presents a good conformability characteristic, and the simulated results are confirmed with the measurements of the fabricated prototype.

“…The reported antenna covers dual bands (2.4 and 5.2 GHz) and a single band (2.4 GHz) for the PIN diode in the ON and OFF states, respectively. Two different types of frequency-reconfigurable antennas are reported in [8] for multiband applications. The reported antenna covers three bands: the Wireless Fidelity (WiFi) band, the Worldwide Interoperability for Microwave Access (WiMAX) band, and the WLAN band, for different biasing conditions of PIN diodes.…”

Low-Profile Frequency Reconfigurable Antenna for Heterogeneous Wireless Systems

et al. 2019

A low-profile (0.21λ g × 0.35λ g × 0.02λ g ) and a simply-structured frequency-switchable antenna with eight frequency choices is presented in this paper. The radiating structure (monopole) is printed on a 1.6-mm thicker, commercially-available substrate of FR-4 ( r = 4.4, tanδ = 0.020). Specifically, it uses three PIN diodes in the designated places to shift the resonant bands of the antenna. The antenna operates at four different modes depending on the ON and OFF states of the PIN diodes. While in each mode, the antenna covers two unique frequencies (Mode 1 = 1.8 and 3.29 GHz, Mode 2 = 2.23 and 3.9 GHz, Mode 3 = 2.4 and 4.55 GHz, and Mode 4 = 2.78 and 5.54 GHz). The performance results show that the proposed antenna scheme explores significant gain (>1.5 dBi in all modes) and reasonable efficiency (>82% in all modes) for each mode. Using a high-frequency structure simulator (HFSS), the switchable antenna is designed and optimized. The fabricated model along with the PIN diode and biasing network is tested experimentally to validate the simulation results. The proposed antenna may also be combined in compact and heterogeneous radio frequency (RF) front-ends because of its small geometry and efficient utilization of the frequency spectrum.

“…The ground plane is close to the ground plane size of 8 mm × 35 mm, which is very small.

An integrated multi‐band monopole antenna with three radiating strips having a compact structure to provide a double‐wideband operation in an Internet of Things (IoT) device is studied and presented. The proposed antenna is very suitable for the heterogeneous multi‐access network integration trend applications in mobile or fixed IoT devices, which can cover the 4G and 5G operating frequencies, the vehicle‐to‐everything and dedicated short range communication band from the IEEE 802.11p based wireless technology, the WiFi 6 band from the IEEE 802.11ax, the WLAN, and the WiMAX operating frequencies. The proposed antenna is manufactured on a single side of high quality FR4 substrate, which has a compact dimension of 8(L) × 8(W) × 0.8(T) mm3, and is composed of multibranch strips, namely, multiple curved shapes, L shapes to be embedded in the IoT device as an built‐in antenna. There are two operating bands designed between 2355‐5000 and 5112‐7000 MHz with well radiation efficiencies. The measured results show that the two operating bands are satisfied with reflection coefficient better than −6 dB, and total efficiencies of higher than 44% to 83%. In addition to that, the proposed antenna with multiband operation having a single side structure is simple to manufacture, low cost, low profile, and compact advantages.
