Fig. 1 is an application scenario diagram of a home intelligent gateway provided according to some embodiments of the present disclosure. As shown in fig. 1, the terminal device 100 is connected to a server 300 through a home intelligent gateway 200 network, and the terminal device 100 is a mobile phone, a television, or the like. With the development of WIFI transmission technology, in order to facilitate the home intelligent gateway 200 to adapt to different terminal devices 100, the home intelligent gateway 200 provides wireless WIFI signals in two frequency bands of 2.4GHz and 5 GHz. The home intelligent gateway 200 provides wireless WIFI signals of two frequency bands of 2.4GHz and 5GHz simultaneously, so that the transmission speed of the wireless WIFI signals is faster, the signals are more stable, and the home intelligent gateway 200 saves more power.

In order to realize that the home intelligent gateway 200 provides wireless WIFI signals in two frequency bands of 2.4GHz and 5GHz, a combiner is required to be used in an antenna device in the home intelligent gateway 200 to combine the wireless WIFI signals in two frequency bands of 2.4GHz and 5 GHz. Fig. 2 is an internal block diagram of a home intelligent gateway according to some embodiments of the present disclosure. As shown in fig. 2, the home intelligent gateway 200 includes a combiner 400.

In some embodiments, the combiner is implemented by using a capacitive sensor, and is affected by the accuracy of the capacitive sensor, so that index fluctuation is large, and production consistency is poor.

In some embodiments, the combiner is implemented by using a distributed transmission line, which has the problems of larger size and high cost. Taking the 2.4G frequency band as an example, the quarter wavelength corresponds to 30mm, and even if the dielectric constant is considered, the branch length is often about 20mm, so that the requirement of miniaturization of the combiner is difficult to adapt.

The filter is formed by combining LC circuits, and the lumped parameter filter formed by LC devices is easy to realize in a low frequency band, and is difficult to realize in a high frequency band due to the influence of device parameter fluctuation, welding spots and other distribution parameters.

In some embodiments, the extending direction of the fourth series transmission line 4411 is different from the extending direction of the fifth series transmission line 4412, so that the second series transmission line 441 forms a bend at the connection between the fourth series transmission line 4411 and the fifth series transmission line 4412. Illustratively, the fourth and fifth series transmission lines 4411, 4412 are bent at 90 °. The arrangement of the second serial transmission line 441 in a bent shape facilitates the second serial transmission line 441 to be matched with the combining component 420 and the first via 430 to fully utilize the space on the substrate 410, so as to reduce the layout size of the combiner 400.

In some embodiments, the extending direction of the fourth series transmission line 4411 is the same as the extending direction of the first series transmission line 431, and the extending direction of the fifth series transmission line 4412 is perpendicular to the extending direction of the first series transmission line 431. Illustratively, the fifth series transmission line 4412 extends in the direction of where the first via 430 is located.

In some embodiments, as shown in the orientation of fig. 8, the fourth series transmission line 4411 extends along the width of the substrate 410 and the fifth series transmission line 4412 extends along the length of the substrate 410.

In some embodiments, the fourth parallel transmission line 4421 and the fifth parallel transmission line 4422 are respectively arranged in parallel with the second serial transmission line 441.

In some embodiments, the second series transmission line 441 has a length of 10-15mm and a width of 0.2-0.4mm. The second serial transmission line 441 has a length of 12mm and a width of 0.3mm, for example. In some embodiments, the fourth series line 4411 has a length of 8-10mm and the fifth series line 4412 has a length of 2-5mm.

In some embodiments, the fourth and fifth parallel transmission lines 4421 and 4422 have lengths of 7-10mm and line widths of 0.4-0.7mm. Illustratively, the fourth and fifth parallel transmission lines 4421 and 4422 have a length of 8.5mm and a line width of 0.5mm.
