Project objects
Scope
- Design and construct a portable wireless device which can accurately measure the speed of rotating object.
Specific Aims
- Design and produce a metamaterial absorber with resonate frequency of 2.4GHz.
- Design and fabricate a planar dual-antenna which can transmit and receive signals with limited crosstalk.
- Design a software system which can calculate the rotation speed.
Background & Significance
- Rotation speed measurement devices widely used in industries.
- Current popular rotation speed measurement devices, such as laser tachometer, use visible light.
- Can not use if line of sight blocked.
- Intend to change – use Electromagnetic Wave instead
Key Requirements
- Metamaterial Absorber shall absorb at least 90% (-10db) power at 2.4GHz when it has same polarization with antenna.
- Dual antennas shall work at 2.4GHz and the crosstalk between 2 antennas shall be less than -40dB.
- Portable system shall be operational up to 50cm from the rotating object.
- Portable system shall accurately measure the rotating object in both low and high speed.
Proposed Approaches
- Method exploited - ‘Divide-And-Conquer’.
- The entire project can be decomposed into several aspects.
