This paper presents the design of near-field focussing reflector metasurface antenna for wireless power transfer applications at 5.8 GHz. The metasurface is designed using an array of $13times 13$, 1-bit phase qunatized crossed dipole type elements with unit cell volume of $0.49lambda times 0.49lambda times 0.13lambda (lambda$ is corresponding to frequency of 5.8 GHz). The proposed metasurface reflector illuminated by a microstrip patch antenna is capable of focussing the radiation to a single spot. The focus can be varied from $1.5-3lambda$. The far-field results of the antenna show a broadside radiation with gain of 12.3 dBi and 3dB beamwidth of 9.5° and 7.8° in xz and yz-planes, respectively.

A planar microstrip probe at a frequency of 16 GHz is designed and simulated with various biological samples. In addition to its small size, non-contact nature, and direct coupling to tissue, the proposed sensor is able to couple high power with the tissue enabling abnormality detection with good sensitivity. Study of $S_{11}$ parameter has been carried out for the presence of lipomas (fat masses) under the skin. Also, simulation results for basal cell carcinoma (BCC) and malignant melanoma (MM) type of skin abnormality are discussed. Between healthy and BCC skin tissue, an amplitude contrast of roughly 8 dB and frequency deviation of about 660 MHz is obtained. The results suggest that the proposed probe is simple to make and provides a economical method for detecting skin cancer quickly and accurately.

This work explores a compact dual band trident-shaped monopole antenna for 5G applications. The designed antenna has dimension $32 times 25times 1.524 text{mm}^{3}$. The structure of the antenna consists of symmetric trident-shaped patch with arrow shaped strip in the center. The L-shaped slots are used to modify the defected ground plane and to obtain the dual band characteristics. The proposed design demonstrates the measured impedance bandwidths in the range 3.27-3.88 GHz (lower band) and 4.85-5.23 GHz (upper band), respectively. The radiation efficiency for both the operating bands are above 76%, the realized average gains are 1.28 dBi and 1.7 dBi across both the operating bands, respectively. The radiation patterns of the monopole antenna are acceptable for 5G applications. The proposed design is modeled and simulated using CST microwave studio. The simulated results agreeing well with the fabricated antenna.

In this paper the uniform circular array (UCA) of triangular patch antennas for generating the orbital angular momentum (OAM) beam is presented. The 8-element microstrip triangular patch UCA is designed to work at the 5.45 GHz which generates the OAM beam of mode $l=-1$. The sidelobe levels of microstrip triangular patch antenna are considerably lower than the other patch shapes and hence it is used in uniform circular phased array for the generation of OAM beam.

This article elucidates the switchable absorption properties by employment of a thin film of vanadium dioxide. Gold patterns are designed over a quartz substrate which exhibit plasmonic resonance. In the insulator state of vanadium dioxide, the absorption of electromagnetic waves is lower as compared to its metallic state. The insulator-metal phase transition alters the electrical, thermal and optical properties of vanadium dioxide. The proposed absorber exhibits more than 98% absorption at 2.95 THz and 4.6 THz in the metallic state. Below the transition temperature, vanadium dioxide behaves as an insulator which allows transmission of electromagnetic waves. By varying the temperature, the rate of absorption can be changed due to variation of refractive index and permittivity of vanadium dioxide. Numerical simulations have been conducted using CST 2021 software.

In this paper, co-design of power amplifier (PA), low pass filter (LPF) and antenna is presented for a beamforming network for 5G base stations. The targeted frequency range is 3.3-3.6 GHz. A class AB PA is designed using harmonic load pull technique to extract power from the harmonics and hence maximum possible power added efficiency (PAE) over a wide bandwidth. A high performance LPF is designed and integrated with the PA for improved harmonic suppression. The antenna is a U-shape ultra-wideband (UWB) antenna, which originally showed tilted dipole like radiation pattern. The antenna is modified to obtain a directional pattern in the broadside direction while maintaining the pattern over the desired frequency range. The PA, LPF and antenna are integrated on the same substrate and overall results are investigated. It is a good candidate for RF beamforming network for the base stations with user tracking capability.

This paper presents a technique to enhance the antenna efficiency of a printed circuit board (PCB) based modified H-plane horn antenna. Improvement in antenna efficiency is obtained by correcting the phase error on the radiating aperture using a modified feed geometry. It also helps to improve input matching. This modification does not increase the overall rectangular dimension of the antenna when compared to a conventional H-plane horn antenna. As an example, a modified H-plane horn is presented for the 24-24.25 GHz ISM band. It increases the antenna efficiency by at least 30% over the conventional PCB-based horn. The best |S11| for a conventional horn in the same substrate which could be achieved is − 6 dB. In comparison, the modified horn provides a 10 dB matching bandwidth of at least 516 MHz. Other advantages are low side lobe levels and small 3 dB beamwidth.
