Effect of the cut-out zone without copper under the antenna The device under test is a PCB of size 40 mm x 20 mm, again with a GNSS chip antenna designed for small tracking devices. Small mobile GSM/GPS trackers are common for pets, humans or assets. GNSS chip antennas operate as loop antennas which are […]
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 […]
Today we tell you the ingredients you will need in order to reproduce the world’s first IoT potato to power a GLOBIO BLE Beacon. The potato is planned as a side dish. The starter I already explained. It was the world first´s IoT Sandwich listed here. We will show you how to make the main course […]
The DUT is a GPS loop antenna planned for a small GSM / GPS tracker of an estimated 40 mm x 20 mm. The goal of this test is to detect the bandwidth of the GPS antenna and the interference of meat placed close to the final GPS tracker. Check of the ingredients of world´s […]
New GSM / GPS / Bluetooth module adapter for STM32 Nucleo, Arduino, Intel Galileo plus compatible PCBs Your ideas? Your wishes? Your recommendation? Your advice? I will listen to you. Before I started to write the IoT / M2M Cookbook I asked business friends what they would like to pay for such a book. A […]
I have an (IoT) dream – Tesla in front of Burger King I took this photo on my business trip on Monday to an electric vehicle charge station. On the way back to my home I got tired and decided to stop, take a nap and to get some coffee. I left the highway and […]
Today we tell you the ingredients you will need in order to reproduce the world’s first IoT sandwich. The sandwich is planned as a starter. We will show you how to make the main course and the dessert later. Ingredients for the IoT sandwich For the PCBs 9 different PCB shapes (3 different cut-out zones […]
The device under test is a PCB of size of 40 mm x 20 mm with GNSS antenna for a small tracking device again. The first DUT in this series of test is listed here. Small mobile GSM / GPS trackers are common for pets, humans or assets. Chip antennas operate as loop antennas which […]
The device under test is a PCB of size of 40 mm x 20 mm with 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 antennas and are usually unaffected by being near to the […]
For a few bucks you can get such a Radiation Measurement System (RMS) to measure Radiation Patterns and Total Radiated Power (TRP) from a 3-axis rotation of your wireless IoT / M2M application. While Radiation Patterns and Total Radiated Power (TRP) is usually measured in an anechoic chamber to avoid reflections to affect the measurement, […]
