Friis Transmission Equation • PTest= Power of Test Antenna • PStandard= Power of Standard Gain Antenna • GTest= Received Gain of Test Antenna • GStandard= Received Gain of Standard Gain Antenna
Free Space Microstrip Measurement Results Raw Data Normalized Data HPBW= 113° - 58° = 55°
Microstrip Chamber Measurement Results Raw Data Normalized Data HPBW= 119° - 58° = 61°
Reflector Chamber Measurement Results Raw Data Normalized Data HPBW= 98° - 82° = 16°
Future Work • Continue Testing System • Ensure LabVIEW Positioning is exact • Continue Improvement to GUI
