Radiation patterns are measured with a CMT Planar 804/1 Vector Network Analyzer in a Howland Company 3100 Chamber equivalent. Phase Center is 9 inches above the Phi positioner. Flat surface measurements are done with the antenna centered on a 100 x 100 mm, 0.35 mm thick brass plate. Curved surface measurements are taken by placing the antenna on a curved surface made of 0.35 mm thick brass.

Taken from CST simulation Keep the main element clear of any non-metal objects (such as plastics) on top of it by at least three millimeters (see Figure 15). Figure 15: Top clearance Similarly, keep the two long sides of the mFlexPIFA clear of any non-metal objects by at least two millimeters (see Figure 16). For metal objects, the top side of the mFlex should be kept clear by at least two millimeters and the bottom side of the mFlex at least 12 millimeters (see Figure 17). 2 mm Figure 16: Non-metal side clearance Figure 17: Metal side clearance A one-millimeter clearance should be observed from the ground wall to any non-metal object (Figure 18). A 15-millimeter clearance should be observed for metal objects (Figure 19).

Figure 19: Metal ground wall clearance Mounting the mFlexPIFA in a situation that does not allow for these clearance recommendations may change the gain characteristics stated in the datasheet, which could impact overall range of the wireless system. The ideal material for the mFlexPIFA to be mounted on (for maximum performance) is brass. However, as previously mentioned, the mFlexPIFA can tolerate other metallic surfaces and thicknesses and still radiate effectively. Depending on the type of material, the mFlexPIFA may be detuned. The coaxial cable feeding the mFlexPIFA should be routed away from the antenna. Do not run the coaxial cable over the top of the mFlexPIFA or near the tip of the main element. The cable should be routed perpendicular to the side of the mFlexPIFA (this is the way the cable comes assembled) or away from the ground wall. These options are shown in Figure 20. Perpendicular to the Side Away from the Ground Wall Figure 20: Recommended cable routing As with any antenna, do not place objects near the antenna (except as described in the next section). Other objects, such as an LCD display, placed near the antenna may not affect its tuning but can distort the radiation pattern. Materials that absorb electromagnetic fields should be kept away from the antenna to maximize performance. The following are some common things to keep in mind when placing the antenna: Embedded Wireless Solutions Support Center: http://ews-support.lairdtech.com www.lairdtech.com/wireless 330-0243-R2.1 19 Americas: +1-800-492-2320 © Copyright 2018 Laird.

However, due to the adhesive, there are limits to how much the antenna can be flexed and still remain secured to the device. The mFlexPIFA should not be flexed in a convex position with a radius less than 60 millimeters. Going smaller than this may result in the antenna peeling off the surface over time. Should a tighter radius of curvature be required, we recommend that you contact Laird/LSR Design Services for assistance. Figure 21: Convex mounted We do not recommend mounting the mFlexPIFA in a metal-enclosed concave position. In this scenario, the limiting factor is performance. The ground plate of the antenna is pressed closer to the main element. The fringing fields developing off the end of the element are responsible for most of the radiation. In a concave position, the fringing fields are adversely affected and gain suffers. This can also potentially create a Faraday’s cage and cancel most of the RF radiation from the antenna. If a concave position is required, we recommend that you contact Laird/LSR Design Services for assistance. Note: The mFlexPIFA is not designed to be twisted or crumpled. The adhesive back should lay flush with the surface on which it is mounted.
