TURNSTILE ANTENNA Russian patent published in 2004 - IPC

FIELD: antenna engineering; circularly polarized antennas operating in high-frequency and very-high-frequency bands.

SUBSTANCE: proposed antenna has balancing unit assembled of tubes which are secured on flat screen and form two-wire closed stub whose length varies with aid of short-circuit made in the form of perforated disk receiving balancing unit tubes. Upper part of coaxial line of first tube is made in the form of single-section quarter-wave matching transformer whose central conductor has its top end connected to central conductor laid in second tube to form open coaxial stub together with this tube.
