1. As H350 does not have a RF connector so for RF line microstrip line is recommended The shorter the better insert loss is less than 0 2dB impedance is less than 50ohm It is recommended to mount H350 module and antenna connector to the same side of layout Add a rr type circuit two parallel device ground pin directly to the main land for antenna matching SSC zl i Figure 7 1rr type Circuit NC 7 2 2 Impedance The RF lines impedance should not exceed 50 ohm 7 3 Antenna Design 7 3 1 Main Antenna Design Requirements 1 Antenna Efficiency Antenna efficiency is the ratio between antenna input power and radiation power The radiation power of an antenna is always lower than the input power due to the following factors return loss material loss H350 LGA Serials Module Hardware User Manual Page 36 of 38 Bs FISOCOM and coupling loss Efficiency of the master antenna gt 40 4dB 2 S11 or VSWR S11 return loss indicates the degree to which the input impedance of an antenna matches the reference impedance 50 ohm S11 shows the resonance feature and impedance bandwidth of an antenna Voltage standing wave ratio VSWR is another expression of S11 S11 relates to the antenna efficiency S11 can be measured by vector analyzer 11 of the master antenna lt 10 dB 3 Polarization The polarization of an antenna is the orientation of the electric field vector that rotates with time in the direction o
