Between 2014 and 2021 a series of seven test light-balloon stratospheric flights took place, with the objectives to test various aspects of vertical electric antenna systems for the Very Low Frequency range. These missions helped to define important risks associated with free-flying large antennas and create effective ways to mitigate them, allowing the successful implementation of a stratospheric VLF transmitter.

A multi-stable fiber reinforced polymer composite helical latticed-based antenna is presented in this paper. The antenna is designed with a reconfigurable deployable Quadrifilar helix topology that exhibits two different stability states. The first state has a linear polarization with an omnidirectional radiation pattern for terrestrial point to point communication. The second state presents a circular polarization with broadside propagation to ensure satellite-ground communication. The antenna was fabricated and tested where measurement results agree notably with simulated designs. The antenna exhibits extremely light weight and great agility making it suitable for portable deployment for areas with diminished infrastructure.

Reconfigurable intelligent surfaces (RIS) have gained a lot of attention due to its ability to perform low-cost beam steering for applications in emerging smart radio environments. An equivalent circuit model for a varactor-loaded microstrip RIS element, covering a wide tuning range and providing accurate physics-based circuit model for both reflection phases and magnitudes for a normal incidence is developed and presented. The circuit model facilitates system level study of RIS-based wireless communication networks with realistic analytical RIS responses as parameter inputs.

Replacing the expensive and bulky network analyzers and moving toward stand-alone measurement equipment is a live topic of research for resonant cavity-based watercut meter sensors. In this paper, we distinguish the cavity’s resonant frequency using transmitting signal amplitude. This frequency is proportional to the watercut of water-oil or water-gas in multi-phase flows. To prove the concept, a resonant cavity sensor (RCS) was fabricated. To improve the transmission coefficient of RCS, an impedance matching circuit was also implemented. Since there is no feedback in the sensing chain, this method is very fast. Moreover, reducing the number of elements leads to a lower cost.

This paper presents the design of a compact metamaterial-based MIMO antenna for 5.8 GHz WLAN applications. The proposed antenna consists of two rectangular patches placed on a low-cost FR4 substrate. A series of metamaterial absorber unit cells are integrated between the two antenna elements to attain a high isolation level of 50 dB. The total size of the proposed MIMO antenna is only 32 x 60 mm2 with a mutual coupling level of less than -50 dB, thus making it an ideal candidate for 5.8 GHz WLAN-MIMO applications.

A time domain discontinuous Galerkin (DGTD)-based framework is developed to analyze three-dimensional organic electrochemical transistors (OECTs). The proposed framework uses a local DG scheme to discretize the (non-linearly) coupled system of the Poisson equation (in electric potential) and the drift-diffusion (DD) equations (in charge densities) in space. To reduce the computational requirements, a dual-mesh scheme, which uses a dense mesh for the DD equations and a much coarser mesh for the Poisson equation, is used. Furthermore, an implicit-explicit time integration scheme, which allows for a significantly larger time-step size, is utilized to efficiently account for the extremely long response time of OECTs. Numerical results are provided to demonstrate the applicability and accuracy of the proposed solver.

We present a new reflectarray technology capable of scanning in two dimensions. The device is a reflective semiconductor chip composed of small two-stage phase delay cavities filled with electrically biased liquid crystal. The scanning is enabled by changes in the AC electrical bias, which modifies the effective dielectric constant of the liquid crystal. This enables each cavity to delay the fields in each stage by as much as 360 degrees. As a result, the two-stage cavity allows nearly independent scanning in two orthogonal planes. The structure operates at a wavelength of 1550nm and is manufactured using a standard damascene process.

Synthetic dielectric breast phantoms are generated by conditional generative adversarial network (CGAN) in this paper. Phantoms produced by the generative neural network are 128 by 128 pixels for frequency 3 GHz. The generated phantoms can be used in electromagnetic simulations for microwave breast imaging (MBI) research and can serve as the training data to develop machine learning algorithms for MBI research.

This work proposed a novel, cost effective miniatur RFID tag antenna for human healthcare monitor. To achieve the conjugated input impedance match between antenna structure and Monza-4 chip (7.17—j74.22 Ω at 915 MHz), the proposed antenna was optimized by coarsely controlling the positions of vias and fine-tuning the gap of coupled patches. To further reduce the height or the size of antenna, the design method based on the 3D-dipole current distribution was presented. Consequently, the proposed tag not only was miniaturized but also got a stable long read range (> 5.0 m) and a wide bandwidth of 71 MHz, regardless of different placed locations of tag on the human body. Adequate agreement between the simulation and measured results was verified experimentally.

Advanced vehicle-to-everything (V2X) communication is expected to require very large data rates, ultra high reliability, and low latency. This motivates the design of antennas able to operate in the mmWave spectrum with sufficient bandwidth and high gain. In this paper, candidate antennas are investigated and Dielectric Resonator Antennas (DRAs) are found to be an effective solution. An aperture-coupled circular DRA made from Rogers 6010 substrate is designed and simulated. The simulated peak gain and impedance bandwidth are 6.4 dBi and 2.51 GHz, respectively. The designed antenna shows potential for use in mmWave vehicular communication.
