SPE-16-08-023/A/WY Page 1 of 15 SPECIFICATION PATENT PENDING Part No: FXUB65.07.0180C Product Name: Minima Embedded Flexible 4G LTE Wide Band Antenna 700-960MHz, 1700-2700MHz Features: Flexible Wideband Antenna Covers worldwide 2G/3G/4G Bands Isotropic Radiation Pattern Highest efficiency in smallest size 67.0x58.0x0.2 mm IPEX 1.37 coaxial cable RoHS Compliant
SPE-16-8-023/A/WY Page 2 of 15 1. INTRODUCTION The patent pending Minima FXUB65 flexible antenna has been designed to cover 4G bands in the 700-2700 MHz spectrum, but also optimally covers 2G and 3G. The antenna has a compact, flexible, modern design, with excellent efficiencies on all target bands. The Minima comes standard with 180mm IPEX cable and connector for easy installation and can also be configured for different cable lengths and terminations. The 67x58x0.2mm FXUB65 is made from flexible polymer material, which is ultra-thin, compact and highly efficient across the 3G and 4G bands. It is installed by a simple “peel and stick” process, attaching securely to non-metal surfaces via adhesive backing. The Minima has been designed with excess bandwidth so that performance is not affected by thicker or thinner plastic surfaces to which it is adhered. It enables designers to use only one antenna that covers all cellular communication frequencies in the IoT market. The Minima antenna has a unique compact geometric design, which has excellent efficiency for its size and isotropic pattern at both low and high bands. This antenna if integrated optimally with enough clearance, can in most cases pass US operator requirements. The antenna performs well at a reasonable distance, typically 20mm, from a ground and has demonstrated ease of integration into complex end user equipment. The FXUB65 Minima antenna has a typical efficiency of more than 50% across the low bands and 64% across the high bands . The Minima is designed to be mounted directly onto a plastic or glass cover. It is an ideal choice for any device maker that desires ease of integration and needs to keep manufacturing costs down over the lifetime of a product. Cable and connector can be customized, contact your regional Taoglas sales office for support.

SPE-16-8-023/A/WY Page 14 of 15 7. Application Note Like all flex antennas, the FXUB65 Minima antenna performance is somewhat sensitive to the routing of the cable during integration. The preferred routing is a “full wrap” or “half wrap”, as shown below where the cable is routed around the long side of the device. Routing over the lower part of the device as shown will also work well. An integration where the cable runs straight off will work, but the performance in the 900MHz band may not be optimal. Avoid running the cable up along the short side or wrapping it around the short side, as these will not work. If a longer cable is needed to wrap around the long side and still reach the module, this is ok, and a longer cable can be easily built. Keep the antenna at least 20mm away from conductors in the end user device. The FXUB65 can be integrated into assemblies over a small ground plane such as a PCB. The efficiency in these cases can sometimes be higher than the antenna alone.
