“…Some small signal parameters were estimated from experimental I/V characteristics (saturation current 10…20 fA, ideality factor 1.2…1.35, series resistance 30-50 ohm) with the zero-voltage capacitance of about 2 fF [9]. The Schottky diode cutoff frequency is around 1.5 THz, more than 10 times that of the upper limit of the W band (75 -110 GHz).…”

“…The symmetrical radiation pattern of the micromachined double folded slot antenna is used to bring at the SD terminal both radiofrequency and local oscillator signals. More recently, a monolithic integrated antenna and SD multiplier for free space W band (75 -110 GHz) power generation was reported in [9]. In these papers the whole front-end was simulated and designed using 3D electromagnetic (EM) analysis and linear/nonlinear circuit techniques.…”

A W band (75 -110 GHz) communication link using monolithic integrated single-diode circuits is proposed. The circuits are based on GaAs Schottky diodes with cutoff frequencies around 1.5 THz integrated with on chip folded slot antennas and near-field 3D printed dielectric lenses. The total chip area is 1.4 × 3.5 mm 2 . The receiver module shows a peak isotropic voltage sensitivity of 12260 mV/mW at 94 GHz, with a noise equivalent power of 12 pW/√𝐻𝑧. These results include the slot antenna and a 3 mm radius 3D printed lens. The transmitter acts as a free-space W band signal generator using the non-linear properties of the diode for frequency multiplication. Multiplication orders up to ×15 are tested for input powers of 10 mW. The generated power is measured by a horn antenna placed at a distance of 100 mm from the transmitter and a 2D map for the frequency range 90 -100 GHz and multiplication orders between ×2…×15 is presented. The two circuits are used to demonstrate W band communication links using 1 kHz amplitude modulated input signals with carriers at 6 GHz, X band and in the Ku band. Voltages of hundreds of mV are detected for a distance of 150 mm between transmitter and receiver circuits and tens of mV at 600 mm. The proposed approach can be used as a low cost and low complexity alternative for point-to-point high-speed wireless communications.

“…Apart from the well-known geometry, for multi-band operations, a compact leaves microstrip antenna patch is preferred. Other important features include a level head, lower exposure loss, and compatibility with microwave compact integrated circuits Bunea et al 2020, Zbitou et al 2006 [2,3]. In the electromagnetic spectrum, the X and Ku bands are independent and back-to-back.…”

Microstrip antennas are low-profile antennas that are utilized in wireless communication systems. In recent years, communication engineers have been increasingly interested in it. Because of downsizing, novelty, and cost reduction, the number of wireless standards has expanded in recent years. Wideband technologies have evolved in addition to analog and digital services. Radars necessitate antenna subsystems that are low-profile and lightweight. Microstrip antennas have these qualities and are suited for radars as an alternative to the bulky and heavyweight reflector/slotted waveguide array antennas. A perforated corner single-line fed microstrip antenna is designed here. When compared to the basic square microstrip antenna, this antenna has better specifications. Because key issue is determining the best values for various antenna parameters when developing the patch antenna. Optimized Neural Network (ONN) is one potential technique utilized to solve this issue, and this work also uses Particle Swarm Optimization (PSO) to enhance the antenna performance. Return loss (S11) and Voltage Standing Wave Ratio (VSWR) parameters are considered in all situations, developed with Advanced Design System (ADS) applications. The transmitters are made to emit in the Ku-band, which covers a wide range of wavelengths. From 5-15 GHz, it is used in most current radars. The ADS suite is used to create the simulation design.
