Confidential Information 1 Summary Sample Photo A.Electrical Characteristics Frequency 2400～2500MHz S.W.R <=2.5 Efficiency 50～60% Polarization Linear Impedance 50 Ohm Antenna Type PIFA B.Material & Mechanical Characteristics Material of Radiator FR4 PCB Cable Type O.D.1.13mm(white) Connector Type Mini Connector for O.D.1.13mm Coaxial Cable Pull Test >=1.0 Kg C.Environmental Operation Temperature -40℃～+65℃ Storage Temperature -40℃～+80℃ 2. Test Result 2.1 RF Performance 2.1.1 S11 Measurement The S11 parameter was performed using a Hewlett Packard E5071C Network Analyzer and SCSZ’s test fixture that was using customer-providing device. We use a 30cm long ferrite de-coupling sleeve to mitigate surface currents on the outside of the testing cable. The matching circuit was shown below:

SCSZ ANT S11 parameter Summary of RS005 (free space testing) WIFI Band 2400 2450 2500 R.L (dB) -7.14 -9.58 -11.24 VSWR 2.47 1.96 1.79 You could also check in detail in below figures. S11 parameter of antenna tested in free space

Confidential Information 2.1.2 Radiation pattern and Gain Measurement An anechoic chamber was used to measure radiation pattern and antenna Gain. SCSZ’s chamber was working from 400MHz to 6GHz. The chamber provides less than –40 dB reflectivity from 400 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 Efficiency parameter was shown below, you could check it.
