Internal Chip Antenna (OEM Modules)
This is a helix type surface mount ceramic chip antenna.
Ideally the product enclosure should be made from fibreglass, light coloured ABS or Polypropylene; other
materials may adversely affect the signal by attenuation, refraction or change in polarisation.
Mounting
If the application demands that the radio is fitted inside a metal enclosure then ensure that the specified
clearances are maintained around the antenna and design in a fibreglass RF window at least as large as the
clearance dimensions but ideally as large as possible.
Radio modules fitted inside a product should be oriented so that the chip antenna will be vertical when the
product is in its normal operating position.
There must be no metal objects within 15 mm radius of the antenna edges.
