A method is presented by which full 3-D antenna pattern measurements can be performed without an anechoic measurement environment. The method is a field compensation technique that allows compensating for the effect of arbitrary incident test zone fields. Simulations are performed to demonstrate that the method works reliably in various kinds of surroundings. The applicability range of the method is estimated in terms of the accuracy of the determined far-field antenna pattern with a given uncertainty in individual measurement values. Finally, measurement results are presented that are in line with the simulations and verify the functioning of the method.
