Special Issue Information

Dear Colleagues,

Electronics publishes high-quality manuscripts on advances in the state of the art in wireless communications. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments, prototypes, and new applications) are encouraged. The general scope of the transactions includes, but is not limited to, the following: modulation and coding , detection and estimation, diversity techniques and equalization, propagation and channel characterization, fading countermeasures, multiuser detection, signal separation and interference rejection, DSP applications to wireless systems, broadband wireless communications, network architectures and protocols, with an emphasis on physical and link layer communication, adaptive antennas for wireless systems, multiple access techniques, space–time processing, synchronization techniques, software radio, resource allocation and interference management, multi-rate and multicarrier communications, security, privacy, and authentication, experimental and prototype results, systems and services, including mobile satellites, wireless local loops, wireless LANs, wireless PBX, and PCS/cellular.

In addition, papers on specific topics or on more non-traditional topics related to specific application areas are encouraged.  Examples include simulation tools and methodologies for design, analysis, rapid prototyping, performance prediction, and cellular system engineering; orthogonal frequency division multiplexing; MIMO systems, and wireless over optical.

This is a dramatic change from previous technologies, which will provide significant challenges as well as new opportunities. For example, beam forming and beam steering (using antenna arrays or SIW) will be possible, given that individual antennas can be much smaller at higher frequencies. At these high frequencies, the wavelength (lambda) is around 1 cm. Thus, the devices are multi-lambda platforms, which means that the position of the antenna itself has become much more critical, replacing the integration aspect, key in previous technologies. These more complex aspects of 5G/6G/LTE/Wi-Fi/BLE and IoT development also make it critical to evaluate multiple implementations in order to optimally identify and adjust trade-offs.

This Special Issue aims to bring together academic and industrial researchers to identify and discuss technical challenges, complex aspects, and new results related to the design and performances of 5G/6G/LTE/Wi-Fi/BLE and IoT antennas.

This paper proposes the design of a compact sub-6 GHz four-port flexible antenna for utilization in 5G applications. A two-arm monopole with a coplanar waveguide feed line printed on a flexible substrate was proposed to shape the single-element antenna. The single element was designed, fabricated, and measured first; then, four copies of the single element were organized on a single flexible substrate to compose the four-port antenna. The MIMO antenna was simulated, fabricated, and experimentally measured. All the simulations and measurements of the flexible single element and MIMO antennas are presented. The presented MIMO antenna showed good impedance characteristics, with a deep level of −24 dB from 3 to 4.12 GHz. The antenna had omnidirectional and bi-directional patterns in the φ = 0° and φ = 90° planes. As an important parameter evaluation for MIMO, the mutual coupling between the different ports was investigated. The diversity gain (DG), the total active reflection coefficient (TARC), the mean effective gain (MEG), the envelop correlation coefficient (ECC), and the channel capacity loss (CCL) parameters were investigated and showed good performance. All the obtained simulation results were in a high degree of agreement with the measurement results, supporting the usage of the suggested antenna in 5G communications. Full article

With the emergence of 5G and satellite communication applications, where millimeter-wave (mm-wave) active phased arrays play an important role, the demand for a highly integrated and cost-effective method to achieve mm-wave antennas is an inevitable trend. Antenna-in-package (AiP) design is therefore becoming a hotspot. This paper presents the design procedure for a broadband silicon-based stacked patch antenna in Ka-band, which realizes a practical AiP structure for phased-array module integration requirements. A stacked-patch antenna on a high-resistivity silicon (HRSi) substrate is demonstrated to effectively extend the bandwidth with the guidance of characteristic mode analysis (CMA).The proposed antenna element and its 2 × 2 array were designed and fabricated using silicon bulk micromachining and wafer-level bonding technology. The measured results from the fabricated antenna prototypes showed that (1) the antenna element had an impedance bandwidth of 13.8% from 26.2 to 30.1 GHz, and the peak gain was 6.1 dBi at 28.9 GHz; (2) the 2 × 2 array realized an impedance bandwidth of 11.4% from 27.2 to 30.5 GHz, and the peak gain was 9.3 dBi at 28.5 GHz.

As the same device may be used for various types of applications, antennas must have the capacity to perform multiple functions. Reconfiguring the polarization, operational frequency, and radiation pattern can create an outcome of multi-functionality. A hybrid, frequency- and pattern-reconfigurable antenna with two V-shaped extrudes in a patch is proposed. To increase the bandwidth of the proposed antenna, the defected ground structure (DGS) phenomenon is presented, which is significant in the bandwidth of 3200 MHz from 2.7 GHz to 5.9 GHz, providing a gain of 3.5 dB. For this design, an FR-4 material was chosen as the substrate, and CST software was used for simulation. Using two p-i-n diodes, the projected antenna illustrates switching for multi-frequency bands such as 1.5, 2.6, 3.2, 5.1, and 8.1 GHz, with a constant radiation pattern and a main lobe direction of 155 degrees. It has C-band, WLAN, cognitive radio (CR), and Bluetooth applications. The proposed antenna displays radiation pattern switching at 3.5 GHz, showing variation between 7°, 158°, 173°, and 175°, and at 4 GHz, it demonstrates switching between 11°, 15°, 165°, and 344°, which defines the hybrid reconfiguration.
