Recommended footprint
F :
Fixation pad. This pad is floating and should not be connected to any signal or
ground areas on the PCB.
I/O :
Should be connected to a 50 Ohms impedance line.
Standard Conditions:
-
FR4 Material (Permittivity 4.4, Thickness 0.8 mm)
-
No metallisation is allowed underneath the antenna area
* For customer specific needs, if the surrounding layout is different, additional SMD matching
components or more appropriate products should be advised by EPCOS.

Notes:
1)
Measured on FR4 90*40 mm EPCOS standard PCB. The area under the antenna is free of
copper. See recommended Footprint.
2)
The values extracted are issued from the three main cuts of
the radiation pattern
f = 0, f = 90, q = -90. Measurement Accuracy 0,3 dB.
