Background

In conventional far field antenna test fields, the transmit and receive antennas are each located at the far field of the other, the two typically being spaced far enough apart to simulate the desired operating environment. The AUT is illuminated by a source antenna sufficiently distant to produce a near-planar wavefront over the AUT's electrical aperture. Far field measurements may be made at indoor or outdoor test fields. Indoor measurements are typically performed in a microwave anechoic chamber. Such dark rooms are rectangular and tapered, and are specifically designed to reduce reflections from walls, floors and ceilings.
