Claim Text:
1. A method for transmitting data using at least two active antennas, wherein each active antenna is surrounded by at least two different parasitic antennas, wherein respective parasitic antennas are respectively coupled to controllable loads, and wherein the controllable loads are respectively coupled to a control circuit, the method comprising: determining, by a signal transmitting device, whether a downlink channel is in a good state according to channel change predictions, channel quality report feedback or uplink data transmission conditions; and if the channel is in the good state, selecting an orthogonal transmitting combination, and adjusting reactance of the controllable loads via the control circuit according to the orthogonal transmitting combination, and bearing the data of the signal transmitting device in a mode command by using a multiplexing mode to transmit data to a signal receiving device; or if the channel is not in the good state, selecting a relevant transmitting combination, and adjusting the reactance of the controllable loads via the control circuit according to the relevant transmitting combination, adjusting transmitting directional diagrams of the active antennas according to a transmitting beamforming vector to transmit data, and bearing the data of the signal transmitting device in the mode command by using a beamforming mode to transmit it to the signal receiving device.
