This work examines the (measured) relationship between the radiation pattern and Error Vector Magnitude (EVM) for an identical transmit/receive pair of microstrip patch antennas operating at 3.5 GHz. The availability and understanding of this type of behavior is becoming increasingly important as the necessary performance of the antenna should be in terms of the fractional bandwidth needed to accommodate data instead of a pure CW representation. For this study, two identical linearly polarized rectangular patch antennas are characterized in a line of sight experiment and the behavior of the antenna pair is observed as a function of the modulated signal. Measured results of EVM vs. elevation angles for the transmit/receive pair of antennas and the experimental set-up are provided.
