Miniature Helical PCB Antenna for LoRa-Tag

LoRa Tag antenna 3D drawing

The antenna design in this LoRa-Tag is based on the application note for the Texas Instruments DN038. The customer’s project objective was to match the antenna to the European 868 MHz band without changing the structure. Text excerpt from the TI application note “There are several ways to tune an antenna to achieve better performance. […]

Selection of antenna for a device in the Internet of Things

The antenna is always the key to success for your wireless application. Each antenna has its benefits and drawbacks. The selection of the right antenna at beginning of a development project, or if you are planning the development of a device around the antenna, could save you a lot of money.

How to build the 50 billion IoT devices? What to do instead of talking?

IoT devices with customised antennas

1. IoT buttons In my region, two IoT buttons caused a buzz and landed in the basket of end customers. One is the Amazon Dash button and the other one is the Gillette order button called Gillette Club Station. LoRaWAN and SIGFOX had no chance as carriers because of the lack of deep indoor coverage […]

Low cost BLE-GPRS-GPS-gateway

Bluetooth-GPRS-GPS-gateway

Are we able to make a mint of money with such a low-cost BLE-GPRS-GPS-gateway? If yes then it makes sense to follow a train of thoughts listed in my IoT M2M Cookbook. Everybody can make such a gateway real for less than USD 15. In my IoT M2M Cookbook – excerpt here: http://www.gsm-modem.de/M2M/m2m_iot_cookbook I explained […]
