efficiency of an antenna relates to its electrical dimensions. To be specific, the 
antenna efficiency increases with the electrical dimensions. In addition, the 
transmission cable from the antenna port of ME936 to the antenna is also part of the 
antenna. The cable loss increases with the cable length and the frequency. It is 
recommended that the cable loss is as low as possible, for example, 
MXHP32HP1000 made by Murata or equivalent. 

The following antenna efficiency (free space) is recommended for ME936 to ensure 
high radio performance of the module:

   

 

Efficiency of the primary antenna: 

≥ 40% (working frequency below 960 MHz); ≥ 

50% (working frequency above 1420 MHz) 

 

Efficiency of the secondary antenna: 

≥ half of the efficiency of the primary 

antenna in receiving band (

≥ 50% @ 1574.42 MHz–1605.89 MHz) 

In addition, the efficiency should be tested with the transmission cable

. 

S11(VSWR) and S21 

S11 indicates the degree to which the input impedance of an antenna matches the 
reference impedance (50 

Ω). 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 with a vector 
analyzer. 

The following S11 values are recommended for the antenna of ME936: 

 

S11 of the primary antenna 

≤ –6 dB 

 

S11 of the secondary antenna 

≤ –6 dB (≤ –10 dB @ 1574.42 MHz–1605.89 

MHz) 

In addition, S11 is less important than the efficiency, and S11 has not strong 
correlation to wireless performance.

 

S21 indicates the isolation between two antennas.   

Isolation 

For a wireless device with multiple antennas, the power of different antennas is 
coupled with each other. Antenna isolation is used to measure the power coupling. 
The power radiated by an antenna might be received by an adjacent antenna, which 
decreases the antenna radiation efficiency and affects the running of other devices. 
To avoid this problem, evaluate the antenna isolation as sufficiently as possible at the 
early stage of antenna design. 

Antenna isolation depends on the following factors: 

 

Distance between antennas 

 

Antenna type 

 

Antenna direction 

The primary antenna must be placed as near as possible to the ME936 to minimize 
the cable length. The secondary antenna needs to be installed perpendicularly to the 
primary antenna. The secondary antenna can be placed farther away from the 
ME936. Antenna isolation can be measured with a two-port vector network analyzer.

 

The following S21 values are recommended for the antenna on laptops:
