This paper presents a novel partially reflective layer (PRL) for improving the impedance and the 3-dB gain bandwidths of a printed antenna operating in X-band. The proposed PRL is constructed by two arrays of two different partially reflective unit-cells (PRUCs) arranged on both faces of the same substrate. The PRL is used as a superstrate over a dual-layer printed antenna. Broader impedance and 3-dB gain bandwidths of about 39.25 % and 41.13% are achieved. Thus, the designed single-layer PRL is very useful for boosting the 3-dB gain and the impedance bandwidths of X-band printed antennas.

This manuscript identifies and describes the main elements in teaching an interdisciplinary short-term applied electromagnetics course on bioelectricity in an online mode. The major takeaway of this study is the identification of enablers for the learning process, when there is no physical interaction between the teacher and the student. The suitability of the assessment methodology when there is no face to face learning is also evaluated during this study.

We propose a novel configuration of an insulator for human-head implanted UWB antenna. The insulator is 3D printed with a biocompatible material and is filled with a deionized water of high dielectric constant and low loss tangent. The proposed compact antenna shows an average gain of −20 dBi in the boresight region for the target frequency of 3–5 GHz band, high enough for the wireless biotelemetry communications.

A wideband dual-polarized metasurface antenna is proposed using characteristic mode analysis (CMA) for Ka-band applications. To achieve the dual-polarization, a primary patch is introduced with orthogonal microstrip-feeds in the same layer with a low profile, low cost and low back lobe level. Furthermore, the single-feed and differential-feed are adopted for vertical polarization (VP) and horizontal polarization (HP), respectively, to enhance the port isolation. A $2times 2$ metasurface is presented for wideband operation and the CMA is used to determine the modal behaviors of the entire structure. Simulation results show that the return losses of both ports are better than 10 dB and the isolation is higher than 20 dB over 30.1-39.6 GHz. The simulated gain ranges 4.7-6.9 dBi and 7-7.5 dBi for VP and HP, respectively.

This paper proposes a remote sterilization technique through microwave radiation. The innovative approach requires the heating of a liquid water film layer, which can be sprayed onto the area of interest. Applications include the deactivation of the coronavirus and other pathogens by physically increasing the liquid film temperature achieving thermal sterilization. The proposed technique can be implemented by various antenna systems and retrodirective arrays. In this study, a dual-polarized antenna array is adopted and designed to increase the transmitted power levels without physically including more antenna elements. As reported in the paper, this dual-polarized approach has the benefit of reduced sterilization time when compared to a single-polarization system having the same number of antenna elements.

In this report, a new design for a reflectarray antenna using mirror configuration will be proposed. By adapting to the two characteristics of a reflectarray antenna that changes beam directions using frequency and polarization, it is possible to realize a multi-scanning beam whose performance is as good as a conventional multi-spot beam with one reflecting mirror. Herein, we examine a scanning-spot beam that changes the beam direction by using frequency in the elevation direction and polarization in the azimuth direction in the Ka band. As a result, the proposed design efficiently covered the desired service area.

This paper introduces a wideband star-shaped planar antenna with a liquid crystal (LC) material at Ka-band. The antenna array consists of the LC cavity and planar antenna elements with a microstrip feedline. Planar antenna array is designed with eight star-shaped patches. To check the LC dielectric constant at Ka-band, the designed antenna is fabricated and measured result of reflection coefficient(S11) ≤ −10 dB shows across the wideband (27 GHz – 40 GHz) without DC biasing with bean scanning from −62° to +5° and gain ≥ 8.15 dBi. The frequency range can be tuned with applied biasing voltage on the LC cavity.

A dual-band dual-polarized aperture-shared antenna array with low blockage effect is proposed. The proposed dual-band array consists a low-band (LB) element and a $4times 4$ high-band (HB) antenna array. The LB element is located at the center of the HB array which is shielded under the LB element radiator. In the normal case, strong blockage effect from the LB on HB elements would exists. By adding split ring resonators (SRRs) along the LB radiator, the LB element scattering in the high-band can be suppressed. As a result, the blockage effect of the low scattering LB element on the HB array is indistinct. The proposed blockage reduction method is suitable for multi-band aperture-shared antenna array.

This paper presents a non-invasive glucose-monitoring sensor that is based on a tunable band reject filter. The filter topology comprises a feeding network at a top layer that excites eight open loop resonators embedded in the ground plane. The shape of the resonators is inspired by the vasculature anatomy of a human arm. The embedded resonators are designed to resonate at 8 different frequencies in order to track the variations of the glucose level across the 1.5 GHz - 2.4 GHz frequency span. Furthermore, the filter's frequency operation is also tuned by relying on integrated varactors in order to enhance the sensor's dynamic responsiveness to glucose variations. The proposed tunable filter is fabricated and tested on diabetic rats, and in a clinical setting. A high correlation between the scattering parameters of the proposed sensor and the variations in glucose levels is noted. A Gaussian Process regression model is also developed using data obtained from experiments. Results demonstrate that the proposed sensor detects glucose variation with an accuracy that reaches 98.55% well within clinically acceptable performance.
