This article presents the design, comparison and performance of three antennae which captures electromagnetic energy from free space. Each antenna is designed to resonate at multiple frequencies, so as to accumulate more energy. The design was performed using HFSS software, after fabrication the results were verified using Network Analyzer. Simulated and practical values of return loss are less than -10dB, Voltage Standing Wave Ratio (VSWR) is less than or equal to 2 at multiple frequencies between 3GHz and 10GHz. These antennae in association with other circuits can be used to capture power from free space. The obtained energy can be used to power low power electronic devices.

Rectifying antenna, electromagnetic energy, energy recycling.
