The near-field wireless information and power transfer system that can support high data rate applications presented in this paper. It was developed by coupling dual-band resonators (DBRs) oscillating at the practical frequencies of 433 MHz and 900 MHz. In turn, the required DBRs were designed applying the slotted ground plane technique. Furthermore, when two 20×20 mm2 DBRs are separated by 18 mm, the power transfer efficiency was measured to be around 60% for both operating bands. Finally, the obtained bandwidth of 9 MHz at the data transfer band allows allocating several resource blocks.

We present the design and simulation of a DOA system composed by a novel 2D stacked Luneburg lens and an antenna array. The non-resonant lens is composed of 7 layers of a dual-diameter structure. The variation in the refraction index is achieved by adding cylindrical air inclusions in a dielectric base material. The results demonstrate that the design is suitable in direction finding applications.

We present a compact wideband antenna operating in the 28 GHz and 38 GHz millimeter-wave spectrum. The proposed antenna is designed on the Rogers RT/duroid 5880 substrate. The proposed antenna has a simple geometry and compact dimensions of 17 mm × 12 mm × 0.79 mm. The antenna design is simulated using the ANSYS HFSS software. The features of the proposed antenna are also compared to similar designs from the literature, to demonstrate the potential of our antenna for use in the targeted frequency band. The results in the present paper indicate that our design is a good candidate for use in future wireless communication systems.

A conical dielectric resonator antenna fed by a rectangular cavity-backed slot is proposed. The design consists of a conical dielectric antenna lying on a cavity-backed slot excited by a coaxial probe. This design aims to block the undesired radiation and enhance the antenna radiation quality to obtain high gain and support exciting high-order modes. Compared to that of other high gain antennas, the proposed design can provide high gain at a lower cost with easy fabrication for dual-pol capability.

This abstract describes the decomposition of a matrix representing a scattering dyadic into characteristic modes. Scattering dyadic, as compared to conventionally used impedance matrices, are independent of numerical method used to compute them and the same characteristic mode formulation can be used for decomposition of composite and inhomogeneous materials. The utilization of scattering dyadic makes it possible to synthesize characteristic modes which are orthogonal over prescribed portions of the far-field sphere, or ex-post decomposition of measured data. The theory is demonstrated on a simple example and its features are discussed.

Propagation loss modeling is considered to be important for the efficient planning of any wireless communication system. We present a novel convolutional neural network (CNN)-based propagation loss modeling based on field measurements in urban scenarios. We consider bird’s-eye images as input data that include the information of buildings, intersections, and roadways. Each image represents a different spatial segment of main propagation paths between a transmitter and a receiver. Multiple feature extraction layers based on CNNs are used. The proposed model shows its superior performance compared with the COST 231 Walfisch-Ikegami model.

This paper presents an exponential flared Vivaldi type antenna in two different modifications that achieved high bandwidth and gain. The proposed antenna has been designed and optimized, considering the integration feasibility of the phased array system. The proposed antenna has been obtained with the bandwidth 5.12-16.34 GHz by optimizing a standard exponential flared Vivaldi antenna topology on CuClad substrate with dielectric constant εr = 2.5. Including a half-circle as a hat notch and slots improve the antenna's directivity. The parametric study on notch elements is provided. The outcome of the parametric investigation is that those notch elements affect the directivity of the radiation characteristic without changing the S parameters due to its symmetrical characteristics.

An experimental device based on a rectangular waveguide is proposed to measure electromagnetic (EM) property parameters of lossy penetrable materials. The frequency band of measurement is 8.2 – 12.5 GHz and the parameters like effective dielectric constant and loss tangent can be measured through a mode-matching method and numerical analysis with a partially-filled waveguide. With the obtained mode and field distribution in the filled materials, the EM property parameters of the material can be inverted. Measurement simulations for typical materials show that the designed device can effectively measure the EM property parameters of penetrable materials and the measurement error of 0.2% can be achieved.

The petal antenna has structural mechanical errors, which causes electrical performance to differ from design values. In this paper, the power pattern variation interval under the same error of standard paraboloid and three groups of shaped surfaces is studied. By performing some numerical simulations using the Monte Carlo method, the antenna generatrix least sensitive to error is found. Results of this paper also indicates that further optimization of the shaped generatrix is necessary.

This paper presents the experimental validation of the detection capabilities of a low complexity wearable system designed for the imaging-based detection of brain stroke. The system approaches the electromagnetic inverse problem via a 3-D imaging algorithm based on the Born approximation and the Truncated Singular Value Decomposition (TSVD). For testing, flexible antennas with custom-made coupling-medium are prototyped and assessed in mimicked hemorrhagic and ischemic stroke conditions. The experiment emulates the clinical scenario using a single-tissue anthropomorphic head phantom and strokes with both 20 cm3 and 60 cm3 ellipsoid targets. The imaging kernel is computed via full-wave simulation of a virtual twin model. The results demonstrate the capabilities for detecting and estimating the stroke-affected area.
