Antenna Chamber Test Setup
Antenna measurements such as VSWR and S11 were measured with an Agilent E5071C vector network analyzer. Radiation patterns were measured with a Rohde & Schwarz ZNB8-4PORT vector network analyzer in a Howland Company 3100 chamber equivalent. Phase center is nine inches above the Phi positioner.

Antenna Placement & Keep Out Region
Antenna Placement
The i-FlexPIFA is designed to be attached to dielectric surfaces encountered in plastic packaging of wireless communications devices. The nominal attachment surface used in its design and characterization is a 120 mm x 70 mm, 1.5-millimeter thick, Polycarbonate sheet.
The VSWR of the i-FlexPIFA is shown below for the following materials and thicknesses outside of these specifications:

Notes:
- Antenna is designed to be mounted on polycarbonate with a nominal thickness of 2.25mm (1.mm - 3mm)
- Diagram is not to scale
