Confidential Information 1 Summary of the Test results The test fixture was made for further testing, which was shown below. 2. Test Result 2.1 RF Performance 2.1.1 S11 Measurement The S11 parameter was performed using a Hewlett Packard E5071B Network Analyzer. We use a 45cm long 1.13 cable to mitigate surface currents on the outside of the testing cable. We used no matching circuit . The S11 parameter was shown below, you could check it. SUC ANT S11 parameter Summary Band 2.3 ~2.7&3.3~3.8&5.15~5.85(GHz) 2.3 2.7 3.3 3.8 5.15 5.85 R.L (dB) -16.59 -11.22 -8.87 -8.96 -8.46 -10.04 VSWR 1.35 1.76 2.13 2.11 2.22 1.92 You could also check in detail in below figures.

Confidential Information 2.1.2 Radiation pattern and Gain Measurement An anechoic chamber was used to measure radiation pattern and antenna Gain. SUC’s chamber was working from 700MHz to 6GHz. The chamber provides less than –40 dB reflectivity from 700 MHz through 6 GHz. A standard horn was used to calibrate the chamber, and we also use a decoupling sleeve to reduce feed line radiation, so we can measure the antenna gain accurately. The Gain parameter was shown below, you could check it.
