2. TESTING CONDITION

   • 2.1 TEST SETUP
     VSWR measurement (S11): Use ROHDE & SCHWARZ ZV8 Network Analyzer with Harbour RG-142 coaxial cable: 1000mm length in free space.
   • 2.1.1 VSWR
     The table as below summarizes concern about Return loss measurement according to The frequency band is based on FWS design. The detail be shown as appendix that is from ROHDE & SCHWARZ ZV8 Network Analyzer

     + 45˚ Polarization : VSWR Performance
     Freq(MHz)	2400	2450	2500
     Free space	1.4	1.01	1.55

     - 45˚ Polarization : VSWR Performance
     Freq(MHz)	2400	2450	2500
     Free space	1.41	1.08	1.47

   • 2.1.2 ISOLATION MEASUREMENT
     The isolation of the dual polarization antenna was measured by ROHDE & SCHWARZ ZV8 Network Analyzer. The way to measured isolation is connect output ports and the other ports mount with 50 ohm matches respectively. The table as below summarizes concern about isolation measurement according to The frequency band is based on FWS design.

     Isolation Performance
     Freq(MHz)	2400	2450	2500
     Free space	-21.94	-24.75	-22.84

3. GAIN MEASUREMENT

   • 3.1 TEST SETUP
     The gain of the antenna was measured by FWS Chamber. The chamber provides less than –30 dB reflectivity from 800 MHz through 6 GHz and a 60cm diameter spherical quite zone. The measurement results are calibrated using both SCHWARZBECK horn standards. A decoupling sleeve is used to reduce feed line radiation
   • 3.2 TEST RESULT
     The peak gain is picked up as table list from Network analyzer in Chamber room, the completely gain plots also be shown as appendix.
