Abstract

The invention discloses a WLAN combiner, a combining method thereof and a coupling window design method of the WLAN combiner. The WLAN combiner comprises a cavity (1), a cavity cover plate, a signal common port (2), a first WLAN channel input port (3), a second WLAN channel input port (3), a third WLAN channel input port (5), resonant cavities (6) and resonant rods (7); and the interior of the cavity (1) includes a first WLAN channel, a second WLAN channel and a third WLAN channel. According to the WLAN combiner, the combining method thereof and the coupling window design method of the WLAN combiner of the invention, WLAN signals of three frequency bands are combined with each other, isolation degree is ensured, mutual interference is avoided, and signals of the three channels can work normally at the same time; a cross coupling technique is adopted, and therefore, under a premise that the number of resonant cavities is not increased, insertion loss is decreased, the isolation degree is improved, and out-of-band suppression is improved; and the size and cost of the WLAN combiner are reduced, assembly and debugging processes are simplified, and the stability and reliability of the device are effectively improved. Therefore, the WLAN combiner has the advantages of small size, excellent parameters, low cost and high reliability.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a WLAN combiner and its combining method and coupling window design method. Background technique [0002] In the WLAN network structure mode, any network terminal in the network accesses the network terminal through the AP. Since the wireless bandwidth is a shared bandwidth, usually an AP accesses 20-30 wireless clients in a project to achieve satisfactory access efficiency. Therefore, in areas with high WLAN user capacity requirements, a WLAN co-frequency combiner is usually used to combine the signals of 2 or 3 APs at the front stage and then connect them to the antenna feeder system. [0003] Currently, WLAN frequency band channels are divided as follows, and each channel occupies a frequency band of 22MHZ. In the 2.4GHZ frequency band, a maximum of 3 non-overlapping channels can be accommodated within the same signal coverage. Such as (2401-2423, 2426-2448, 2451-2473M...
