Project Results
Project Goals
  • Our research and detailed study regarding
    different aspects of RF rectifying circuit
    such as microstrip and patch antenna design
    helped us gain a better understanding of the
    formulation and layout for a charging circuit.
  • Based on our research and guidance from the UTD
    faculty members, we designed a Five Stage
    wireless charging circuit and simulated it on
    AWR software. The simulation displayed an
    efficiency of 50?
  • Using PCB 64 millimeter board, we then
    constructed a Five Stage wireless charging
    circuit capable of functioning for 915 MHz
    operations. Our design of the wireless
    charger circuit consisted of two quarter wave
    whip antennas for transmitting and
    receiving purposes that were impedance
    matched to Schottky diodes and other lumped
    elements.
  • To improve our design for effective wireless
    power transmissions utilizing 915 MHz ISM-band
    source frequency which is compatible with
    commercial devices.
  • Based on our research and preliminary
    experimental verification, we will built a
    multiple stage (Five Stage) wireless charger
    capable of acquiring and converting 915 MHz
    source frequency into usable DC power.
  • By the end of second phase of our design
    project, it is our goal to power a small
    device wirelessly with our proposed circuit
    design.


Project Overview
  • For Senior Design II, we decided to revise our
    rectenna design by building a Five Stage wireless
    charger pump for acquiring optimum DC load. Based
    on our research, 915 MHz source frequency best
    served our purpose in achieving our goal of
    obtaining usable DC power at the output load.
  • Timeline

Project Conclusions/Outcomes
  • Using the new design, we received a better
    output power.
  • Successfully simulated our rectenna design in
    AWR Microwave Office and
  • VSS environment.
  • Successfully completed the design and layout of
    the circuit on the
  • PCB board.
  • Sufficiently rectified Radio Frequencies from
    an antenna .
  • The projects results indicated that we can
    achieve much better efficiency
  • by utilizing better antennas.
  • Overall, it was a useful learning experience
    that helped us gain knowledge related to
    wireless power applications.
