Special Issue Information

Dear Colleagues,

Ultra-wideband (UWB) radio—most notably known for its adaptation in surveillance and diagnostic systems—is perceived as an important technology for emerging Internet of Things (IoT) services with high quality of service. The potential of pulse-based UWB in the design of low-cost and low-power communication devices, but also in the development of precise location and identification services, which is of paramount importance for increasing the security and reliability of IoT-based solutions in industry, logistics, or healthcare. Performance of these systems is highly determined by the radio-connectivity layer, which includes complex antenna structures and passive circuits, or active components, all of which exceed capabilities offered by conventional designs. Application of UWB systems in sensor and IoT networks impose stringent requirements on topology, efficiency, and manufacturing cost of components. From this perspective, development of novel microwave and antenna structures for modern UWB devices oriented towards ensuring seamless and uninterrupted communication in diverse environments remains an open problem.

Development of antennas and microwave components for UWB applications include design of passive structures and active circuits, but also their constraint-aware modeling and optimization with respect to real-world requirements. Advanced topologies for identification, imaging, or ultra-low-power IoT devices/sensors are also of high interest. Furthermore, interference-resistant solutions and topology-based approaches for integration of co-existing radio-communication systems are considered indispensable. Availability of interference-immune geometries is especially important for UWB-driven massive resource-tracking systems and/or secure-access mechanisms.

The objective of this Special Issue is to report novel topologies, design methods, as well as validation schemes of UWB antenna structures and microwave circuits that reach beyond the frontiers of the current state of the art. The topics of interest cover synthesis, design and modeling methods, integration techniques, and optimization algorithms, including but not limited to:

  • Antenna arrays
  • Automated design methods
  • Bandwidth-enhancing methods
  • Co-design of UWB components and neighboring systems
  • Compact antennas
  • Computer-aided design
  • MIMO antennas
  • Miniaturization of antennas and passive components
  • Modeling methods for UWB antennas and microwave components
  • Multi-objective optimization
  • Reduction of interferences
  • Robust design and statistical analysis
  • Surrogate-assisted methods
  • Topology evolution
  • Ultra-wideband amplifiers
  • UWB for IoT and sensor networks
  • UWB antennas for imaging
  • UWB antennas for medical applications

This paper proposes a dielectric slabs-based lens for millimeter-wave beamforming systems. The proposed lens is based on the graded steps of the effective refractive index of the semi-spherical lens. It consists of multiple dielectric slabs that match the selected gradient effective refractive index. These slabs have the same thicknesses and different radii. The slab thickness in this lens should not exceed a quarter of the operating wavelength to keep on a similar effective refractive index of the original semi-spherical lens. A horn antenna is used to examine the performance of the designed lens at 28 GHz frequency in terms of the maximum gain, sidelobe level, and 3 dB beamwidth. Sixteen switchable horn antennas are used to demonstrate lens capability for millimeter-wave beamforming. Every single antenna element is selected individually, thus the dielectric lens steers and enhances the corresponding radiation of the selected element in the desired direction. Full article

Antenna structures for modern applications are characterized by complex and unintuitive topologies that are difficult to develop when conventional, experience-driven techniques are of use. In this work, a method for the automatic generation of antenna geometries in a multi-objective setup has been proposed. The approach involves optimization of a generic spline-based radiator with an adjustable number of parameters using a nested, trust region-based algorithm. The latter iteratively increases the dimensionality of the radiator in order to gradually improve its performance. The method has been used to generate a set of nine antenna designs, representing a trade-off between minimization of reflection within 3.1 GHz to 10.6 GHz and a reduction of size. The properties of the optimized designs vary along the Pareto set from −10 dB to −20 dB and from 230 mm2 to 757 mm2 for the first and second objectives, respectively. The presented design approach has been validated against a genuine, population-based optimization routine. Furthermore, the smallest Pareto-optimal design has been compared to the antennas from the literature. Full article
