4.4.4.2 Range Extender v.2 stand alone
Measurements for the characterization of the antenna radiation pattern were also performed with
Range Extender v.2 not soldered on interposer. In this case the matching components values differ
from the values of the module on the interposer. The matching values of the components are: C20=
1.2pF and C16=1pF.
Figure 19: Range Extender v.2 stand-alone
Gain measurements were performed in an anechoic chamber. The maximum gain was measured at
-10 dBi.
