Abstract: This paper presents the design and analysis of a superdirective rectenna optimized for enhanced RF-to-DC efficiency and realised gain, featuring direct impedance matching between the antenna and the rectifier. Employing passively loaded, low profile strip dipoles on a low-loss substrate, the rectenna achieves a realised gain of $6.9 \mathrm{d B i}$ and an RF-to-DC efficiency of $22.1 \%$ at $-20 \mathrm{d B m}$.
