## **1. Introduction** 

The evolution of IoT connectivity has seen an urgent need for low power applications that can connect thousands of devices to the internet and Narrowband IoT (NBIoT) is a new way to facilitate this demand. For a small compact embedded antenna, the Taoglas NCP.5820 fits will fit in many size challenged designs without performance compromises. 

The NCP.5820 supports Bands 5 (824-894MHz), 8 (880-960MHz) and 20 (791862MHz) providing global NB-IoT coverage and demonstrates excellent efficiency across all bands. 

The tiny antenna measures just 14.1x8.3x2mm. As it is a surface mount antenna it can be easily integrated into even the smallest of devices. It allows device designers to take advantage of all of the benefits of NB-IoT technology, including reduced power consumption and increased battery life; increased system capacity and spectrum efficiency; and extended coverage in both rural and deep indoors environments all with a very small form factor. 

Overall, this antenna is suitable for applications that need to meet the following requirements: 

- Small footprint, low profile design factors 

- SMT Components for assembly accuracy and reliability 

- Excellent antenna efficiency helping to maintain better system gain and hence better device send and receive sensitivity (TRP & TIS) 

- Excellent antenna efficiency to aid lower power consumption and increased battery life 

- Global coverage for mobility and one global SKU 

- 100% quality and performance testing prior to shipping for reliability and consistency 

- Mechanical and environmental robustness across the lifetime of the device
