Special Issue Information

Dear Colleagues,

Antenna and propagation technologies are the backbone of 5G/6G communication, which will play a pivotal role in shaping the future of wireless networks. Antennas act as conduits for data transmission, requiring advanced designs like MIMO systems and beamforming to meet the escalating demands of increased bandwidth and energy efficiency in the 5G and emerging 6G landscape. These technologies enable higher data rates and lower latency, essential for applications ranging from augmented reality to the Internet of Things.

In parallel, propagation technologies govern the ways in which electromagnetic waves traverse different mediums, impacting signal coverage and reliability. With the advent of 5G and the impending launch of 6G, addressing challenges such as higher frequencies and diverse deployment scenarios will necessitate innovative propagation techniques like beam steering and dynamic spectrum sharing. The integration of these advancements optimizes signal propagation and mitigates interference, ensuring the efficient functioning of next-generation networks.

As 5G evolves and 6G looms on the horizon, the seamless synergy between antenna and propagation technologies remains instrumental. This integration not only enhances data transmission efficiency but also unlocks the potential for groundbreaking applications, propelling us into an era where connectivity seamlessly intertwines with every aspect of our lives. Antenna and propagation technologies stand at the forefront, driving the transformative capabilities of 5G and setting the stage for the even more ambitious and interconnected future of 6G communication.

This paper presents a circularly polarized hybrid cylindrical dielectric resonator antenna (HCDRA) over a modified Minkowski unit-cell-based metasurface for 5G n79 band (4.4–5 GHz) and IEEE 802.11n WLAN (5 GHz) applications. The location of the perturbed probe feed mechanism and the asymmetric nature of the metasurface are the factors that influence the circularly polarized (CP) radiation within the DR element. The magnitude of E-field distribution and parametric study of the antenna to obtain the optimized feed location are the pieces of evidence of CP radiation. The return loss (RL) and axial ratio (AR) bandwidths produced by the proposed antenna are 1.837 GHz and 750 MHz with a peak gain of 7.04 dBic. The gain obtained is more than 5 dBic across the offered bandwidth of the proposed antenna. The proposed antenna is fabricated and tested in an anechoic chamber for measured results, and these results closely match with the simulation results. Full article

A novel dual-wideband textile antenna designed for wearable applications is introduced in this study. Embedding antennas into wearable devices requires a detailed analysis of the specific absorption rate (SAR) to ensure safety. To achieve this, SAR values were meticulously simulated and evaluated within a human voxel model, considering various body regions such as the left/right head and the abdominal region. The proposed antenna is a monopole design utilizing denim textile as the substrate material. The characterization of the denim textile substrate is carried out using two different methods. The first analysis included a DAC (Dielectric Assessment Kit), while a ring resonator technique was employed for the second examination. Operating within the frequency bands of (58.06%) 2.2–4 GHz and (61.43) 5.3–10 GHz, the antenna demonstrated flexibility in its dual-wideband capabilities. Extensive simulations and tests were conducted to assess the performance of the antenna in both flat and bent configurations. The SAR results obtained from these tests indicate that the antenna complies with safety standard limits when integrated with the human voxel model. This validation underscores the potential of the proposed antenna for seamless integration into wearable applications, offering a promising solution for future developments in this domain.
