2.4 GHz FlexPIFA Antenna, 100mm Datasheet TEST SETUP Antenna measurements such as VSWR were measured with an Agilent E5071C Vector Network Analyzer. Radiation patterns were 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 were done with the antenna centered on a 1.5 mm thick plate of Polycarbonate. Curved surface measurements were taken by placing the antenna on the inside and outside of different diameter PVC tubing.

2.4 GHz FlexPIFA Antenna, 100mm Datasheet OPTIMAL INSTALLATION GUIDE Strong E-Field Between Plates Fringing Fields Main Element Ground Plate Figure 18 E-Field Radiation from FlexPIFA, Taken from CST Simulation The main element should be kept clear of any non-metal objects (such as plastics) on top of it by at least 3 mm (see Figure 19). Similarly, the two long sides of the FlexPIFA should be kept clear of any non-metal object by at least 2 mm (See Figure 20). A 1 mm clearance should be observed from the ground wall to any non-metal object. Mounting the FlexPIFA 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.

However, as previously mentioned, the FlexPIFA can tolerate other non-metallic surfaces and thicknesses and still radiate effectively. Depending on the type of material, the FlexPIFA may be detuned.

2.4 GHz FlexPIFA Antenna, 100mm Datasheet The coaxial cable feeding the FlexPIFA should be routed away from the antenna.

2.4 GHz FlexPIFA Antenna, 100mm Datasheet As with any antenna, care should be taken not to place conductive materials or objects near the antenna (except as described in the next section). The radiated fields from the antenna will induce currents on the surface of the metal; as a result those currents then produce their own radiation. These re-radiating fields from the metal will interfere with the fields radiating from the FlexPIFA (this is true for any antenna). Other objects, such as an LCD display, placed in close proximity to the antenna may not affect its tuning but it can distort the radiation pattern. Materials that absorb electromagnetic fields should be kept away from the antenna to maximize performance. Common things to keep in mind when placing the antenna: Wire Routing Speakers – these generate magnetic fields Metal Chassis and Frames Battery Location Proximity to Human Body Display Screen – these will absorb radiation Paint – do not use metallic coating or flakes The information in this document is subject to change without notice. 330-0149-R3.4 Copyright © 2014-2017 LSR Page 23 of 31

2.4 GHz FlexPIFA Antenna, 100mm Datasheet Flex Limits of the FlexPIFA One of the unique features of the FlexPIFA is its ability to flex. However, due to the adhesive there are limits as to how much the antenna can be flexed and remain secured to the device. The FlexPIFA should not be flexed in a convex position with a radius less than 16mm. Going smaller than this may result in the antenna peeling off the surface over time. Should a tighter radius of curvature be required, it is recommended you contact LSR for assistance. Figure 22 Convex Mounted The FlexPIFA should not be flexed in a concave position with a radius less than 25mm. In this scenario, the limiting factor is performance. The ground plate of the antenna is pressed closer to the main element. As previously discussed in the introduction of this application note, the fringing fields developing off the end of the element are responsible for most of the radiation. In a concave position with a radius of curvature less than 25mm, the fringing fields are adversely affected and gain suffers. If a tighter radius of curvature is required, it is recommended you contact LSR for assistance. The information in this document is subject to change without notice. 330-0149-R3.4 Copyright © 2014-2017 LSR Page 24 of 31

2.4 GHz FlexPIFA Antenna, 100mm Datasheet Figure 23 Concave Mounted The FlexPIFA is not designed to be twisted or crumpled. The adhesive back should lay flush with the surface it is mounted on.

2.4 GHz FlexPIFA Antenna, 100mm Datasheet Mounting on Metal and Body Loaded Applications The FlexPIFA can tolerate being mounted on conductive surfaces. There will be some detuning of the antenna, which translates into some gain reduction. Even though the FlexPIFA is optimized to work on non-metallic surfaces, it still radiates efficiently due to the fringing fields (Shown in Figure 18). The ground plate of the FlexPIFA carries the adhesive backing; placing the antenna onto a metal surface simply enlarges the size of the ground beneath the main element. Previously the fringing fields only interacted with the small ground of the FlexPIFA - however they are now interacting with the much larger ground. The fringing fields still develop and radiate, but the antenna will no longer tune as well to the 2.4 GHz frequency band. Consequently the VSWR increases and there is some loss in radiated power. If the FlexPIFA cannot meet your range requirements after being implemented on a metal surface, contact LSR Design Services for a custom antenna build to help meet your application needs. Figure 24 FlexPIFA Mounted on Metal Do not mount the FlexPIFA where metal is within 10 mm above the main element (see Figure 26). Not only will this severely limit the radiation pattern (mainly due to the re-radiation problem previously described) it will detune the antenna inside of this range. Similarly, the two long sides of the FlexPIFA should be kept clear of any metal object by at least 5 mm. These keep out requirements pertain to conductive materials only, and are different from those listed in the previous sections which apply to non-conductive materials. In general, it is good practice to always keep metals as far away from the antenna as possible. For the best performance, a spacer should be placed between the FlexPIFA and the conductive surface (see Figure 25). The spacer should be 1.5 mm thick polycarbonate. This will significantly improve performance and tuning of the FlexPIFA on a metal surface. Other non-conductive materials such as ABS plastic can be used; however polycarbonate will provide the best results.

2.4 GHz FlexPIFA Antenna, 100mm Datasheet Figure 25 FlexPIFA Mounted on Metal Surface with 1.5mm Thick Polycarbonate Spacer 10 mm Figure 26 Metal near Main Element For body worn applications, the FlexPIFA can tolerate the presence of the human body. It is not recommended that the antenna be mounted directly on body tissue, this will detune the FlexPIFA. Additionally the human body is an excellent absorber of 2.4GHz RF signals. As a result of this, expect a reduction in range due to the presence of a body. In a body worn application, the ground plate of the FlexPIFA should be closest to the body tissue. The main element should be pointed away from the body. Additionally, for handheld devices the FlexPIFA should be mounted in a location where it will not be covered by the hand. If the antenna is mounted in a location where the main element will be covered or near a human body, ensure that there is at least a 10mm separation distance between the main element and the body as shown in Figure 26. Additionally, when the FlexPIFA is mounted very close to body tissue, use a spacer to create separation distance between the body tissue and ground plate. This will ensure maximum performance and prevent the antenna from detuning. As previously mentioned, the ideal spacer material is 1.5 mm thick polycarbonate.

2.4 GHz FlexPIFA Antenna, 100mm Datasheet Quite often this separation distance between the body tissue and the FlexPIFA is already provided by the enclosure. Figure 27 below is an example of a bracelet with the FlexPIFA integrated inside it. The enclosure provides enough spacing between the antenna and body tissue to prevent any major detuning. The enclosure is made of polycarbonate.
