Purpose: This study presents a novel design of a six-port network based on a modified Schiffman phase shifter operating at a 90±2° phase shift.
Design/ Methodology/ Approach: The research methodology encompasses a comprehensive literature review, the analysis, design and simulation of the novel phase shifter, its integration into a six-port network, layout design and subsequent post-layout simulation, and comparative analysis to evaluate the new design's performance.
Findings: The schematic results showed an operational bandwidth from 5.52 GHz to 12.21 GHz, translating to a fractional bandwidth of 75.47% with a maximum phase error of ±1.8° for the 90° phase shift. Also, the post-layout simulation results from momentum demonstrated outstanding performance with an operation frequency band spanning from 5.52 GHz to 12.21 GHz, representing a factional bandwidth of 75.47% and ±2.1° phase error across the entire band. In addition, good impedance matching was achieved at all the ports well below -10 dB.
Practical Implications: It also finds application in satellite communications, where beamforming enhances signal strength and quality by directing the signal towards specific locations on Earth, and antenna arrays for satellite uplink and downlink antennas adjust the beam direction and coverage area dynamically.
Social Implications: The social impact of this work includes high-performing communication devices for current and future generations, more accurate measurements, particularly wearable devices in healthcare for monitoring human vitals, weather monitoring systems, high-precision radar systems, wireless gadgets, high-data-rate communication systems, and Internet of Things (IoT) devices.
Originality and Value: The study contributes to the existing body of knowledge by introducing an innovative design that addresses the limitations of phase accuracy and bandwidth in Six-Port Networks.
