APPLICATION SPECIFICATION 5.0 ASSEMBLY GUIDELINE The flex antenna comes with an adhesive 3m9077 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: 622435 DATE: 2019/08/15 DOCUMENT NUMBER: AS-2123300100 SHEET No. 2.
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 pattern at least 5mm as shown in figure 5.2.1. If the cable crosses into the antenna flex, the antenna performance will be degraded.

APPLICATION SPECIFICATION 6.0 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 6.1.0. The plane ground size is 90mm*90mm and we move the plane ground to four locations for each test. The antenna performance is better with larger distance between antenna and parallel plane ground at high band.

APPLICATION SPECIFICATION 6.4 ANTENNA RF PERFORMANCE WITH DIFFERENT CABLE LENGTH Six cable length have been evaluated and these states are shown in figure 6.4.0. The cable length is 50mm, 100mm (reference metal), 150mm, 200mm, 250mm and 300mm. The antenna performance with different cable length are shown in figure 6.4.1~6.4.8. When the length of cable is greater than 200 mm or less than 50 mm, the performance of low frequency will decrease obviously. We suggest the cable length is 100mm, 150mm and 200mm.
