Multiple aerial

Abstract

The invention relates to a multiple antenna which is used for solving the condition that the channel signal quality deteriorates under mobile environment and the problem of difficult design in a narrow space; the multiple antenna comprises a conducting plate, a main transceiving antenna and an auxiliary receiving antenna, the main transceiving antenna is arranged on the conducting plate, is used for receiving or transmitting multiband signal, comprises a circuit board and metal wires, wherein, the metal wires are formed on the surface of the circuit board and wind the circuit board; the auxiliary receiving antenna is arranged on the conducting plate, is used for receiving multiband signals, and comprises two parallel antenna units which are provided with a body respectively and are electrically connected on the line of the body; the line is provided with a signal feed-in end, thus the two antenna units respectively receive signals with different frequency bands, so that multiband signals can be transceived in a very limited space through the antenna with good isolation degree and packet relevant parameters.

Description

technical field [0001] The present invention relates to a composite antenna, and in particular to a composite antenna for transmitting and receiving multi-band signals. Background technique [0002] In a wireless communication system, due to the movement of the receiving end or the transmitting end, the signal transmission channel will weaken with time, and then the phenomenon of channel fading will occur, which will deteriorate the signal quality of the channel in the mobile environment, resulting in the loss of wireless communication data. The transfer rate drops. The existing practice is to use Mobile Receive Diversity (MRD) to overcome the above problems, hoping to improve the quality of wireless communication transmission through diversity antennas, and the performance indicators that determine the effectiveness of diversity antennas mainly There are two: one is the isolation between antennas, and the other is the envelope correlation coefficient. [0003] However, as...

Problems solved by technology

[0003] However, as clients have higher and higher demands on lightness, lightness and compactness, wireless communication devices must also be designed in a smaller size to meet the needs

Therefore, if more than two multi-frequency resonant antennas are designed in a narrow space, it is usually impossible to obtain good isolation and acceptable packet-related parameters
