A Novel Corrugated-Shank Anchor-Shaped Antenna for Wireless Power Transfer

In this paper we propose a new class of anchor-shaped antenna referred to as corrugated-shank anchor-shaped suitable for angular misalignment resilience. This new topology to operate at 360 MHz differs from previously published anchor-shaped antenna [1] by introducing corrugations in the shank of the anchor for stronger magnetic fields. The results suggest a 10% of power transfer efficiency (PTE) improvement with respect to that of the generic anchor. This improvement is achieved when considering misalignments in the elevational direction. This design can be used as a guideline for future misalignment-free wireless charging modalities integrated into clothing.
