  abstract: Significant advancements in the electronics industry and the use of low power portable devices in the consumer electronic applications have motivated researchers to develop different variety of wireless solutions. Most of these portable devices are battery-operated, requiring periodical recharging. This dissertation presents the study of different coil geometries for developing low-power wireless inductive link as a solution for battery-less gadgets. The developed wireless inductive link also addresses the power loss limitations to enhance power transfer efficiency. Different coil geometries used as both transmitter and receiver coils, are investigated through mathematical modeling and using COMSOL (Finite Element Method) simulation. Achieving better power transfer efficiency over a relatively wider distance between coils is the prime objective in most of the wireless power transfer systems, but it often suffers from power loss in the coil vicinity. One of the viable methods will be to reduce the power loss by field beaming for increased intensity. With this aim, three multi-turn coils of solenoid, spiral and conical are designed and simulated using COMSOL platform to determine the field strength. It is observed that the conical coil produces highest self-inductance of 8.63 µH with a field strength of 1.542 Wb at the switching frequency of 13.56 MHz. Another group of single turn coils based on spiral, square, and rectangular geometry are designed and simulated using HFSS software at a switching frequency of 220 kHz. The performance of these single and multi-turn coils are evaluated to show that the conical and spiral are best suited as transmitter and receiver coils. In addition, the LCC topology with class-E power amplifier design is demonstrated with the coupling factor k = 0.1 using ADS software to reduce the power loss comparatively over an increased coil separation distance. Subsequently, two lab-scale wireless inductive links are constructed for experimental m…
