Claim:
1. A single radio frequency double-stream transmission apparatus, comprising: 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; wherein: the active antenna is connected with the radio frequency link, the parasitic antennas are respectively connected with the parasitic reactor, distances from respective parasitic antennas to the active antenna are the same, and angular spacing between adjacent parasitic antennas is and the reactance control circuit is configured to adjust the parasitic reactor to make reactance values of any one pair of parasitic antennas in mirror symmetry around the active antenna be different and reactance values of remaining pairs other than the respective any one pair of parasitic antennas in mirror symmetry around the active antenna be equal.
