Embodiment Construction

[0040] In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0041] refer to figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the array antenna of the present application. The array antenna in this embodiment includes: an active antenna 110 , a parasitic antenna 120 , and a control circuit 130 . Wherein, the number of active antennas 110 is at least two, and each active antenna 110 is coupled to a transmitting or...

Abstract

The invention discloses an array antenna and a signal transmitting and receiving method and device. The array antenna comprises at least two active antennas, wherein every active antenna is wound with at least two different passive antennas, every passive antenna is coupled to a controllable load, and the controllable load is coupled to a control circuit. According to the array antenna, the at least two active antennas are provided, every active antenna is wound with the at least two different passive antennas and every passive antenna is coupled to the controllable load, so that when channels are in good conditions, the volumes of the channels can be adjusted by adjusting the controllable loads connected with the passive antennas, and when the channels are not in good conditions, by adjusting the controllable load coupled with the passive antennas simultaneously and adjusting the transmitting diagram of the active antennas according to adjustment vectors, the error rate can be reduced, and meanwhile, miniaturization can be achieved.

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 ...
