Department of Electrical and Computer Engineering
Results of Antenna with Inset Feed Matching
Project Goals
RMSW201 MEMS(Switching Method)

• Resonant frequencies shall be two commercially
  available GPS frequencies (1.227GHz and 1.575GHz)
  with a 24MHz Bandwidth
• Switching resonant frequencies shall be
  controlled by MEMS technology
• Patch antenna shall be linearly polarized
• Received signal shall be matched to 50O using
  Inset Feed Matching

Conclusions

• ADS model and simulations met project
  specifications
• Fabricated antenna in progress
