An efficient machine learning assisted array synthesis (MLAAS) method is proposed for practical array designs under mutual coupling and platform effects. By introducing machine learning methods, the impact of the electromagnetic environment on the antenna element is learned and utilized to build surrogate models for active element patterns and S- parameters. Compared with conventional methods, the proposed MLAAS is able to achieve great prediction accuracy based on limited numbers of full-wave simulations. Moreover, the algorithm is able to deal with array design problems with variable element numbers, which is validated using a practical antenna array design task.

The importance of satellite communications in the 5G and beyond 5G ecosystem has been widely recognized. Low orbits and the constant movement of satellites demand for adaptive antenna arrays in ground terminals. In this paper, a single patch element is designed for the K-band, broadly used in satellite communications. The antenna exhibits wide bandwidth and high switchable polarization performance (axial ratio < 3 dB over 2.2 GHz). All results sustain that this structure is a great candidate to implement in larger arrays used when broadcasting from space.

Presented in this paper are the premier results for human body shadowing at 300 GHz. The main-beam and partial blockage effects from a 3D physical model of human body in a typical indoor corridor environment for line-of-sight (LoS) conditions is analyzed. The analysis is based on ray-tracing simulations carried out for the manifold transmitter (TX) and receiver (RX) locations. Results reveal that the proposed novel approach to study pedestrian blockage by means of beam spot size from high gain horns requires a different perspective from countermeasures to combat the likely severe shadowing losses.

A wideband high gain printed ridge gap magneto-electric (ME) antenna with surface mounted conical horn for millimeter-wave applications is presented in this paper. Printed ridge gap waveguide (PRGW) technology is adopted to achieve a low-profile feeding structure to excite the dipole backed by a rectangular cavity. As a gain enhancing technique, a surface mounted conical horn, made from a very thin copper sheet is placed over the ME dipole antenna to achieve a realized gain of more than 15.3 dB. The proposed design exhibits a bandwidth of 7.5 GHz starting from 26.5 GHz up to 34 GHz. The proposed antenna is considered as a good candidate for millimeter-wave applications such as the future sixth generation (6G) of cellular communications.

The COVID-19 disease recognized as pandemic in 2020 created worldwide shortage of medical resources causing hospitals to admit only the severe cases and leaving the rest to selfcare. The identified covid19 patient with non-life-threatening stage had to monitor the disease progression based on the escalation of symptoms or do imaging tests like CT scans, x-ray. The imaging method while reliable comes with its own limitation and risks of exposure. In this paper, we checked the efficacy of utilizing Cardio-Pulmonary Stethoscope (CPS) to monitor the COVID-19 patient and assess the disease progressive status. The simulations were ran on anatomically realistic human model with infection at various location, size and spread reflecting real COVID-19 infected lungs. The least detectable size of injury was found to be the ellipsoid of ~0.9 cubic cm, and the most consistent result was observed in the healthy lung with water content of 20%. The results presented in this paper suggest that CPS could be used as the alternative to CT scans for continuous monitoring.

In this paper, a microfabricated W-band tapered slot antenna (TSA) integrated with a rectangular micro-coaxial line (RμCL) to substrate integrated waveguide (SIW) transition is proposed. To integrate the vertical end-fire TSA array with the horizontally planar feed network in W-band, the transition from an SIW to an RμCL is designed. Then, a linear TSA array is built and achieves a bandwidth from 85 to 100 GHz $(S_{11} < -10 text{dB})$, which can be expanded to a two-dimensional scanning array. The linear array prototype is then fabricated and measured. The measured results show good agreement with the simulated results.

In this work, a low radar cross section (RCS) wideband antenna array is proposed through array-level scattering cancellation. Two types of Vivaldi antenna elements with the same radiation performances and different scattering phase are developed. With these two types of elements, a low scattering Vivaldi antenna array (16×16) is proposed in a chessboard configuration. A reference array with a single type of antenna element is also developed. For radiation, both antenna arrays operate over 8–12 GHz and have similar performances. For scattering, the proposed Vivaldi antenna array achieves an average of 10 dB monostatic RCS reduction over 6–18 GHz under normal incident waves, illustrating the effectiveness of the proposed RCS reduction technique.

This paper presents a K-band (17.7-19.7 GHz) beam steerable phased-array antenna for satellite communication (SATCOM) application. The microstrip patch antenna with PIN diode switches loaded can provide 2-bit phase resolution, thereby realizing the two-dimensional beam scanning. To illustrate the feasibility of this method, we used the reconfigurable 2-bit element to make a modular sparse subarray. Through the subarray splicing technology, full-wave simulation was performed on the regularly arranged 7 subarrays. The simulation results show that the array antenna has a stable left-handed circularly polarized (LHCP) radiation pattern, which can be steered to an elevation angle of $45^{circ}$. For all directional beams, the sidelobe levels (SLLs) and axial ratio (AR) performance can be maintained well.

In the last decade, body-centric communications have taken on great relevance in the field of Wireless Mobile Communications and with a wide range of applications, such as medical, emergency, military, geopositioning, in the logistics industry, among others. An essential part of these applications is carried out by wearable antennas. This paper presents the design of a wearable patch antenna, using materials and accessories for clothing. The antenna has been designed to work at the 4.15 GHz frequency of the Band C (satellite systems) and which has also been studied to be implemented in 5G technologies. The radiant patch was designed with a metal button (used as an accessory in blue jeans), and the simulated dielectric substrate was made of the same jean textile material with a relative permittivity of 1.6 and a thickness of 1.56 mm. Results of the radiation pattern, gain, reflection coefficient, and efficiency under numerical analysis with specialized software. The good results of the gain stand out, being this one of 8 dBi, and the efficiency of 76.88 % was obtained.

Cardiovascular diseases (CVDs) remain the dominant cause of mortality globally and are of an increasing trend. Generally, coronary stent placement is a pervasive treatment to combat CVDs. However, the cardiovascular stent employed as the passive expanded support in the blocked artery frequently introduce a postoperative complication called in-stent restenosis. The innovative self-reported stents integrated with biosensors can offer effective diagnosis and treatment of in-stent restenosis. In addition, the use of biotelemetry is essential in the interaction with physiological signals in the vessel's lumen, ensuring continuous monitoring of internal conditions within a vessel. This paper presents two compact dual-band microstrip antennas with encapsulation and without encapsulation that can implement power and data transmission. In particular, the 1.4 GHz Wireless Medical Telemetry Service (WMTS) band and 2.45 GHz Industrial Scientific and Medical (ISM) band have been allocated for wireless power transfer and biotelemetry, respectively. The proposed stent antennas employ meander slots on the radiating patch, which can achieve an ultra-small volume of 5 × 5 × 0.64 mm3. Moreover, the antenna configurations, reflection coefficient values, and surface current distribution plots are compared between the encapsulated and unencapsulated antennas.
