APPLICATION SPECIFICATION 5.0 ASSEMBLY GUIDELINE The flex antenna comes with an adhesive TESA 68537 for assemble onto the plastic wall of the system. The surface should be smooth with Ra<1.6um, and need to clean the surface before sticking this product. The antenna cannot be placed on a metallic surface. 5.1 HOW TO TEAR FLEX RELEASE PAPER REVISION: A ECR/ECN INFORMATION: TITLE: EC No: 619266 DATE: 2019/06/19 DOCUMENT NUMBER: AS-2125700100 SHEET No.
APPLICATION SPECIFICATION 5.2 CABLE BENDING During the assembly of the antenna in a device, the cable needs to be positioned away from the antenna flex to achieve best performance. The cable must be away from the Flex edge at least 5mm as shown in figure 5.2.1. If the cable bends into the antenna flex, the antenna performance will be degraded.

APPLICATION SPECIFICATION 6.0 RF PERFORMANCE AS A FUNCTION OF IMPLEMENTATION 6.1 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT LOCATIONS WITH PARALLEL PLANE GROUND Four locations with parallel plane ground have been evaluated and these locations are shown in figure 6.1. The plane ground size is 90mm*90mm and we move the plane ground to four locations for each test. The distance between the antenna and the parallel plane grounding has some influence on the low frequency performance of the antenna.

APPLICATION SPECIFICATION 6.4 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT CABLE LENGTH Six cable length have been evaluated. The cable length is 50mm, 100mm, 150mm (reference metal), 200mm 250mm and 300mm. these states are shown in figure 6.4. The cable length should be more than 100mm. The resonance frequency shift to lower and the antenna performance will decrease obviously at 824-960MHz band when the cable length is less than 100mm. FIGURE 6.
