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 an 80 mm x 40 mm, 1.6-millimeter thick, Polycarbonate sheet.
The VSWR of the i-FlexPIFAmini is shown below for the following materials and thicknesses outside of these specifications:
