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 […]

Update IoT / M2M Cookbook, 3 hour Antenna Tutorial, IoT at Electronica in Munich

IoT M2M Cookbook

This quarter I have a lot of IoT / M2M news for you: 1. Update IoT / M2M Cookbook Since 4 weeks the update is on the server, listed here: More than 12 pages are related to ceramic chip loop antennas for GPS/GLONASS and Bluetooth. Loop antennas have no hand effect and will not […]

GPS antenna selection for a GSM / GPS tracker – DUT 3

GPS chip loop antenna temperature drift

Interference of temperature on GPS antenna resonant frequency The device under test is a PCB of size of 40 mm x 20 mm, again with a GNSS antenna for a small tracking device. Small mobile GSM / GPS trackers are common for pets, humans or assets. Chip antennas operate as loop antennas which are magnetic […]

Helical GPS antenna versus GPS chip antenna

Q: I came across a blog of yours some years back. By chance are you still offering assistance with GPS related antenna solutions? If so, we are trying to find a replacement for a Sarantel helical antenna.  We need to match or improve upon the performance of the Sarantel product. We are looking into Maxtena’s […]
