Abstract

The application discloses an array antenna and a method and device for transmitting and receiving signals. Wherein, the array antenna includes at least two active antennas, wherein each active antenna surrounds at least two different parasitic antennas, and each parasitic antenna is respectively coupled to a controllable load, and the controllable load is respectively coupled to a control circuit catch. By arranging at least two active antennas, each active antenna surrounds at least two different parasitic antennas, and each parasitic antenna is respectively coupled with a controllable load, when the channel is in a good state, the controllable coupling with the parasitic antenna is adjusted By controlling the load, the channel capacity can be adjusted. When the channel is not in a good state, the controllable load coupled with the parasitic antenna can be adjusted at the same time, and the transmission pattern of the active antenna can be adjusted according to the adjustment vector to reduce the bit error rate. , and at the same time, miniaturization can also be realized.

Description

technical field [0001] The present application relates to the communication field, in particular to an array antenna and a method and device for transmitting and receiving signals. Background technique [0002] Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) systems allow multiple antennas to transmit and receive multiple spatial streams at the same time, and can distinguish signals sent to or from different spatial orientations. Using the MIMO system at the sending end or receiving end can enable multiple parallel data streams to be transmitted at the same time, improving channel capacity. At the same time, using the MIMO system at the sending end or receiving end can significantly overcome channel fading and reduce the bit error rate. [0003] The prior art provides a MIMO system, which is composed of multiple active antennas, and each active antenna is connected to a transmitting or receiving link, and the transmitting or receiving direction of each ...
