Project Results
Project Goals

• 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
• antenna design.
• 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.

• Research on the mediums for efficient wireless
  power transmission.
• 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.

Project Overview

• We initially researched on various ways by which
  power could be transmitted wirelessly including
  the induction coil method, laser beam and radio
  frequency.
• Timeline

Project Conclusions/Outcomes

• 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.
