This paper presents a 3D-printed hemispherical lens integrated with flower-shaped stub antenna for liquidmixture characterization. The proposed lens antenna is designed, fabricated, and integrated with the ultra-wideband planar antenna. A high impact polystyrene (HIPs) is selected to design the 3D-printed lens antenna by using the fused deposition modelling (FDM) technique, due to low loss 3D-printed material. The optimum the dimensions of the lens antenna are obtained by using the 3D EM Simulation CST Studio, which is used to investigate the performance of the antenna, e.g., gain, radiation pattern and reflection coefficient. To discriminate the liquid content in ethanol-water mixture, the level of the transmission coefficient (S21) is detected. The proposed sensor system offers various preferable features, e.g., non-destructive method and non-contact measurement. Five samples, e.g., 60%, 65%, 70%, 75%, and 80% ethanol in the ethanol-water mixtures, are measured and performed to generate the extraction model. The proposed sensor also offers other advantages, e.g., real-time monitoring and no life-cycle limitation.

“…On the other hand, the pattern bandwidth is related to the relationships between radiation pattern, gain, and polarisation. There are five primary categories of ultra-wideband (UWB) antennas, and they include helical antennas, frequency-independent antennas, log periodic antennas, horn antennas, and resonant antennas [3]. The first four categories are based on conventional wideband antenna designs [1][2][3], in contrast to the relatively recent introduction and widespread use of resonant antennas.…”

“…However, there is a substantial amount of variance in the spectrum occupancy across the various service providers. The Federal Communications Commission (FCC) has drawn attention to an issue that involves the inefficient use of spectrum in its entirety [3]. The Cognitive Radio (CR) system is one solution that might be considered for this effective utilisation of the radio spectrum.…”

Ultra-wideband (UWB) communication systems may make use of a miniature dielectric resonator antenna. A 50 ohm microstrip line is included into the modified T-shaped feed network to produce strong coupling and some bandwidth augmentation; the antenna element itself is a rectangular low permittivity ceramic block with a dielectric constant of 9.4. Simulations and measurements of the antenna's performance in a range of 3100–5500 MHz reveal an impedance bandwidth of 55.8% and a Voltage Standing Wave Ratio (VSWR) of 2, making it well-suited for ultra-wideband (UWB) uses.

In this research article, the design and fabrication of a miniaturized flexible rectifier at 24 GHz for wireless power transfer to wearables is presented. The proposed circuit consists of a shunt topology rectifier including a single stub impedance matching network. Conventional PCB fabrication technique is used for the prototyping of the proposed flexible rectifier. It has a total footprint of 5.29 cm 2 . The proposed rectifier exhibits a good trade-off between compactness and RF-to-DC conversion efficiency. The implementation on a very thin substrate (130 µm) makes it durable for wearables applications. Experimental results of the proposed rectifier show an output DC voltage of 2.0 V across an optimal load resistance of 250 Ω and measured RF-DC conversion efficiency of 23% for an input power of 17 dBm at 24 GHz.
