Abstract: This tutorial focuses on the fundamentals, importance and the method of estimating uncertainty in antenna radiation pattern measurements. The tutorial would begin with a brief review of antenna measurement ranges and basics of gain measurement. Outlining the need for reporting a statement of uncertainty in any gain measurement, the tutorial will then look at the different factors that contribute to uncertainty in pattern and gain measurement in a free-space range. Data from recent measurement efforts will be employed for illustration. Special effort will be made to show some examples of the antenna measurements including omni-directional antennas, directional antennas, circularly polarized antennas, reconfigurable antennas, tunable antennas, null steering antennas, and beam steering antennas, etc. /p>

Key words: Gain Measurement, Horn, Measurement Errors, Multipath interference, Pattern measurement, Two Antenna Method, Uncertainty Analysis
