Active integrated electrically tunable polarization transmit-receive planar antenna

The invention relates to an active integrated electrically tunable polarization transmit-receive planar antenna, and belongs to the technical field of satellite communication. The antenna comprises a dual-polarized antenna panel, an emission intermediate-frequency amplifier amplifies an L-band signal and then sends the L-band signal to a common port of an emission intermediate-frequency power divider for equal-amplitude in-phase power division, one port of the emission intermediate-frequency power divider is connected with an emission port of a first duplexer through an emission horizontal polarization link, and a common port of the first duplexer is connected with a horizontal polarization port of the dual-polarized antenna panel to realize feed-in of horizontal polarization waves; and a second port of the emission intermediate-frequency power divider is connected with a transmitting port of the second duplexer through the emission vertical polarization link, and a common port of the second duplexer is conne
