Wideband Voltage Doubling Detector with Improved Sensitivity
Abstract: The voltage doubling detector can be used to improve sensitivity in field strength meters, RF sniffers, Tuned Radio Frequency receivers and wireless power harvesting. To further boost the detector’s sensitivity, we utilize broadband transformers to efficiently transfer energy between antenna and detector. This paper presents three wideband transformers that can improve voltage sensitivity up to 6.5 times.

HFSS-Based Helix Antenna Design Optimization and Simulation
Abstract: This project uses HFSS (High-Frequency Structure Simulator) to simulate, develop, and analyze the performance of a helix antenna for (a particular purpose, such as broadband wireless or satellite communication). Because of their distinctive structural characteristics, helix antennas are well-suited for a variety of high-frequency applications by balancing compactness, high gain, and wide bandwidth. In this work, we parametrically analyze important design parameters including pitch, radius, number of turns, and wire …
