Abstract

In this study we compare helix and patch array antenna characteristics for wireless power transfer (WPT). It will be shown that the helices offer higher link efficiency for a similar beam scanning limit compared to patch antenna elements. We provide 12-by-12 element planar array results for both cases at different element spacings. The frequency band of interest is ISM 2.4-2.5GHz and we do the comparisons in this range. It is concluded that helix elements, when used as an array, offer significant improvements for wireless power link efficiency, whilst also offering a reasonable beam scanning range.
