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. A: Vertical polarised monopole […]

The journey to develop the Gillette order button

© Harald Naumann - Currently only available in Austria, Gillette offers its customers the capability to order new razor blades at the touch of a button.

In 2016, a creative team in Frankfurt had the idea of developing an IoT push button for ordering goods via a cellular module. In principle, something similar to the Amazon Dash button, only using a GSM radio instead of Wi-Fi. A first, and a tricky learning curve for the engineering team. The developers in the […]
