Latest Patents

One of his latest patents is the "High permittivity dielectric microstrip dipole antenna." This invention features a miniature microstrip dipole antenna constructed on a high permittivity dielectric substrate, allowing for compact compatibility with microwave monolithic integrated circuit (MMIC) technology. The design includes two dipole arms coupled to opposite faces of the substrate, which are connected to a microstrip transmission line through a tapered balun. This innovative balun efficiently transforms unbalanced signals to balanced signals and vice versa, enhancing the antenna's performance. Additionally, a ground plane is incorporated to improve radiation directivity, utilizing a shallow cavity formed between the substrate and the ground plane.

Another significant patent is the "Wide band voltage controlled R-C oscillator for use with MMIC technology." This invention presents a wide band tunable microwave oscillator that does not rely on varactors or inductors for oscillation. Instead, it employs a voltage variable resistor coupled to a first MESFET, which supplies capacitance and amplifies the signal to create an RC oscillator. This design takes advantage of the gate capacitance of the first MESFET and the gain from using an active element within the feedback loop, showcasing a novel approach to microwave oscillation.
