Radiation Patterns and Total Radiated Power (TRP) tested yourself

Turn table and special antenna to measure radiation pattern

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, […]
