A transmit-receive antenna, which has controlled polarization relates to radio engineering, in particular to antenna technique and may be used for studies of depolarization phenomena in real communication lines, also it is possible to use antenna for preventing unauthorized access. A transmit-receive antenna, which has controlled polarization, comprises a the first and the second phase changers, a doublet, an annular antenna, the first and the second antenna switchers, an amplifier with controlled transfer ratio being proportional to, an adder, a frequency converter, an intermediate-frequency amplifier, a detector, a control processor,an amplifier with controlled transfer ratio being proportional to, an amplifier with controlled transfer ratio being proportional to, an amplifier with controlled transfer ratio being proportional to, an oscillator, a power divider. The technical result is automatic tuning to polarization of wave received with maximal transfer ratio of correlation polarization and changing ellipticity in accordance to a preset program of ellipticity and direction of ellipse rotation. |
