AbstractSince 1957 two antennas have been designed for the Microwave Position-fixing System. Both antennas were of the conventional pillbox type. The first was a large-aperture high-resolution antenna which was later replaced with a smaller antenna because the motor-drive unit lacked sufficient capacity to rotate the larger antenna smoothly. The performance of the smaller antenna was found to suffer on short ranges because of side-lobe interference. To correct for these two deficiencies, a third antenna has been built, consisting of a folded pillbox design. This new antenna has a pattern beam-width of 2.3° and side lobes of the order of less than -30db.
