Select an appropriate frequency that is compatible with commercial
devices (2.4 GHz).
Design, test and optimize a rectenna (rectifying antenna)
matched to the source that converts Radio Frequency into usable DC.
By the end of Senior Design II, it is our goal to power a small device
wireslessly with our rectenna design. We initially researched on various ways by which power could be transmitted wirelessly including the induction coil method, laser beam and radio frequency.
Timeline We decided on developing a wireless transmittal device based on radio
frequency to complement the greater ranger factor in our design.
We researched and studied in detail the different aspects of RF circuit
design such as microstrip design, impedance matching and patch
Based on our knowledge from IEEE papers we designed a simple RF
rectifying circuit and simulated it on AWR software. The simulation
successfully displayed an efficiency of 55%.
Using PCB 64 millimeter board we then designed a microstrip rectenna,
consisting of a 2.4 GHz patch antenna impedance matched to a
schottky diode and other lumped elements. Successfully simulated our rectenna design in AWR Microwave Office
and VSS environment.
Designed rectennas consisting of patched or detachable antennas.
Laid out our rectenna design on the microstrip board.
Could not sufficiently rectify Radio Frequency from antenna
to illuminate LED.
The rectenna design received a lot of noise distortion.
We will reevaluate our design in the second part of the project.
Overall, it was a useful learning experience that helped us gain knowledge related to wireless power applications.
