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 […]

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


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: I explained […]

Antennas tests – preparing a PCB for a device in the Internet of Things

Calibration of the VNA on PCB with embedded antenna

Calibration of the VNA on PCB with embedded antenna The calibration of the VNA (Vector Network Analyser)  for a PCB with embedded antenna is difficult. The final antenna with all components except the wireless module should be mounted inside the final enclosure. The wireless module will be replaced by the probe. The three calibrations of […]

Antenna Tutorial -Self-made PCB antenna for NB-IoT and GSM for cost US$ 0

Self Made Embedded Antenna Design versus Chip Antenna The wireless Internet of Things has a need for inexpensive wireless modules and antennas. An LTE-Cat-NB1-module (NB-IoT) will cost less than US$ 6 at 1K order. A self-made NB-IoT antenna on PCB could cost US$ 0. Within 60 minutes you will learn which is commercially and technically […]
