NANO mXTEND TM : MINIATURE AND HIGH EFFICIENCY BLUETOOTH/WI-FI ANTENNA USER MANUAL NANO mXTEND TM (NN02-101) 2 Last Update: May 2022 USER MANUAL NANO mXTEND TM (NN02-101) NANO mXTEND TM MINIATURE AND HIGH-EFFICIENCY BLUETOOTH/WI-FI ANTENNA NN02-101 NANO mXTEND TM | Bluetooth & Wi-Fi Operating range: 2400 – 10600 MHz Best for: 2400 – 2500 MHz Dimensions : 3.0 mm x 2.0 mm x 0.8 mm 3 Last Update: May 2022 USER MANUAL NANO mXTEND TM (NN02-101) What is the NANO mXTEND TM ? The NANO mXTEND TM is the smallest Virtual Antenna ® chip to date. Featuring a size of only 3 mm x 2 mm x 0.8 mm, this off-the-shelf chip antenna has been designed to fit almost every IoT device from entry-level to high-end products. The NANO mXTEND TM is enabled by Virtual Antenna ® technology, thus featuring the unique properties of this class of products: easy to use; versatile, and broadly tunable. The NANO mXTEND TM is available for Bluetooth, Wi-Fi, Wi-SUN, and any wireless connectivity protocol operating in the 2.4 - 2.5 GHz band. Due to Ignion’s proprietary Virtual Antenna ® technology, this chip antenna is non-resonant and therefore broadly tunable, enabling additional frequency bands to be supported by the same antenna part and released in the future. As with every other Virtual Antenna ® chip, the NANO mXTEND TM is available through Ignion’s Antenna Intelligence Cloud tool, enabling predictable design and performance throughout the entire product development cycle. Moreover, the NANO mXTEND TM is built on a glass epoxy substrate, making its manufacturing broadly available and therefore resilient against shortage. Material: The NANO mXTEND TM antenna booster is built on a glass epoxy substrate. What is the NANO mXTEND TM used for? The NANO mXTEND TM is suitable for embedding an antenna into any wireless device requiring optimum performance in a small, cost-effective package for operating in the Bluetooth/Wi-Fi/Wi- SUN ISM 2.4 GHz frequency bands, including:  Asset Trackers  Smart Tags  Earphones and Headsets  Wearables  Logistic Trackers  Health sensors  Animal Trackers  Security Sensors  Service Buttons  Environmental Sensors  IoT Developer Kits  Wireless Sniffing Sensors 4 Last Update: May 2022 USER MANUAL NANO mXTEND TM (NN02-101) What differentiates the NANO mXTEND TM from other chip antennas? Like every other Virtual Antenna ® product, the NANO mXTEND TM is frequency neutral, meaning that its frequency response is not determined by the antenna component but designed by the electronics engineer. Virtual Antenna ® technology provides the broadest range of connectivity options with desired antenna performance in the smallest ever form factor. This unique technology enables the whole mXTEND TM range of components to become tiny, off-the-shelf, surface-mount (SMD) electronic chips while still providing connectivity with multiple frequency bands and meeting the requirements of most wireless devices’ architectures and form factors. Being non-resonant, the whole antenna performance can be customized through a shorter and easier design cycle by means of a matching circuit, while benefiting at the same time from a robust, reliable, and cost-effective manufacturing process because of the chip, SMD form factor. Also, the NANO mXTEND TM ‘s architecture is not using ceramic materials to achieve miniaturization, which ensures a pervasive availability of raw materials thus making the supply chain resilient to shortage and price fluctuations. 5 Last Update: May 2022 USER MANUAL NANO mXTEND TM (NN02-101) Click to view other useful NANO mXTEND TM guidelines: HOW TO EMBED A VIRTUAL ANTENNA ® MECHANICAL SPECIFICATIONS ASSEMBLY AND MANUFACTURING PACKAGING 6 Last Update: May 2022 USER MANUAL NANO mXTEND TM (NN02-101) Chapter Index The NANO mXTEND TM for Bluetooth/Wi-Fi 9 CORNER MOUNTING CONFIGURATION 9 MATCHING NETWORK 11 VSWR AND TOTAL EFFICIENCY 12 RADIATION PATTERNS, GAIN, AND EFFICIENCY 13 EDGE MOUNTING CONFIGURATION 14 MATCHING NETWORK 15 VSWR AND TOTAL EFFICIENCY 16 RADIATION PATTERNS, GAIN, AND EFFICIENCY 17 MECHANICAL SPECIFICATIONS 18 DIMENSIONS, TOLERANCES, AND RoHS 18 INK COLOR RANGE 18 RECOMMENDED FOOTPRINT FOR THE NN02-101 19 ASSEMBLY AND MANUFACTURING 21 PACKAGING 23 7 Last Update: May 2022 USER MANUAL NANO mXTEND TM (NN02-101) How to embed Virtual Antenna ® Design with Virtual Antenna ® in 1-2-3 https://ignion.io/design-center/tutorials-webinars/ STEP 1: Place the antenna component 1. Select one corner of your PCB 2. Ensure your ground plane meets the NANO mXTEND™ clearance area restrictions 3. Respect a keep out space around the booster. Keep at least 5mm distance from metallic objects Look here for an example of antenna placement STEP 2: Design your matching network 1. Through a combination of inductors & capacitors obtain 50 Ohms of antenna impedance to optimize the transfer of energy to your antenna 2. It is critical to fine-tune your MN throughout the entirety the design process to achieve your desired frequency response Look here for an example of a matching network for a Virtual Antenna ® product application via simulation STEP 3: Test your device 1. Perform a field test in which your antenna is placed in its final housing. Fine-tune the MN if needed. 2. Use a network analyzer to adjust mismatch 3. Test the antenna ’s efficiency with an anechoic chamber Look here for a short video tutorial on how to test your antenna.
