Abstract
Embodiments of the present disclosure provide a single radio frequency double-stream transmission apparatus, wherein the apparatus includes: a radio frequency link, a reactance control circuit, a parasitic reactor, an active antenna and an even number M of parasitic antennas, wherein M is larger than 2; the radio frequency link is configured to generate a radio frequency signal; the active antenna is connected with the radio frequency link, the parasitic antennas are respectively connected with the parasitic reactor, the distances from the parasitic antennas to the active antenna are the same, and the radian between adjacent parasitic antennas is the parasitic reactor may be adjusted by the reactance control circuit to make the reactance values of any pair of parasitic antennas in mirror symmetry via the active antenna be different and the reactance values of the rest pairs of parasitic antennas in mirror symmetry via the active antenna be equal respectively.
