Abstract

We provide total radiated power measurements at millimeter-wave frequencies using a reverberation chamber and a power-calibrated vector network analyzer capable of measuring wave parameters. We compare total radiated power results obtained from two different approaches. In the first approach, applicable when the terminals of the antenna under test are accessible, the total radiated power is calculated directly from forward and reflected waves. In the second approach, when we cannot access the terminals of the antenna under test, the total radiated power is calculated from measured forward and reflected waves at the receive antenna taking into account chamber loss. The results from the two different approaches have excellent agreement, and are within the measurement uncertainty. The uncertainty in our total radiated power measurements is below 2%.
