<p>A novel miniaturized fourth order Hilbert fractal rectifier antenna for collecting ultra-short wave RF electromagnetic energy is proposed. The receiving antenna is miniaturized by using the fourth-order Hilbert fractal structure and the slow-wave cross-finger structure, with antenna sizes of 274.86mm × 144.38mm, seven resonances are excited and form a wideband, which locates at 100-300MHz. In the rectifier part, the third order voltage doubling rectifier circuit is designed, which is composed of three sets of Schottky diodes and filter capacitors. The maximum rectification efficiency of this circuit is greater than 80% in simulation and 78% in measurement. The experimental results show that the rectifier antenna has great potential to collect energy in the electromagnetic environment with abundant ultrashort wave energy.</p>
