## **1. Introduction** 

The evolution of IoT connectivity has seen an urgent need for a low power way to connect thousands of devices. The Extensis NCS series of NB-IoT embedded antennas are the smallest form factor antennas on the market to facilitate this demand. 

This part no. the NCS.5820 supports **Bands 5** (824-894MHz), **8** (880-960MHz) and **20** (791-862MHz) and demonstrates excellent efficiency in providing global NB-IoT coverage. This antenna will allow the device manufacturer to enjoy mobilization between all bands so that the device can be used in more than one region with more than one carrier. On the contrary, an antenna covering only one band will have less mobility and will not be suitable for international roaming over Low Power Wide Area networks. 

With a super low profile height of 1.6 mm and a footprint of just 11 x 20mm, the surface mount antenna 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. For testing, it can be supplied on the NCSD.5820 evaluation board, see section 5.2. 

Typical applications include Remote monitoring / Smart meters, Network devices, Smart cities & buildings, Manufacturing automation, Agriculture / Environment and asset tracking. 

Ease of integration and exceptional performance of this antenna make it the perfect starting point for any NB-IoT device design. It is also an ideal choice for cost-sensitive

applications considering also that the material used for this antenna is lower cost than the traditional ceramic NB-IoT antenna. Overall, this antenna is suitable for applications that need to meet the following requirements: 

- Small footprint, low profile design factors 

- Long battery life of up to 10 years is required 

- Deep indoor penetration with +20dB link budget compared with GSM is required 

- Low cost, with an industry target of < $5 per radio module. The material used for this antenna is lower cost than the traditional ceramic NB-IoT antenna 

- High security from proven LTE-based security mechanisms 

- A worldwide 3GPP industry standard on operator-managed networks in licensed 

   - spectrum 

- Possibility of up to 100x more devices per cell compared with GSM
