The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2, the device for controlling switching of signal frequency bands of an antenna according to the embodiment of the present invention includes a substrate 1, a sliding sheet 2, a guiding pressing block and a plurality of groups of fastening pressing blocks 4, where the substrate 1 is located at the bottommost layer, and the whole substrate is an approximately rectangular strip circuit board. A plurality of groups of signal transmission baselines are distributed on the substrate 1 and are used for transmitting signals of a specified frequency band.
In this embodiment, as shown in fig. 4a and 4b, the signal transmission baselines are uniformly distributed on the substrate 1 along the horizontal direction, that is, the intervals between every two adjacent groups of signal transmission baselines are uniform. Each group of signal transmission baselines comprises a, b, c, d baselines, wherein baselines a and d are signal input ends of a specified frequency band, baselines b and c are signal output ends, and in the vertical direction of the substrate 1, the baselines a and b are positioned on the left side of the substrate 1 and on the same straight line, and the baselines c and d are positioned on the right side of the substrate 1 and on the same straight line; in the horizontal direction of the substrate 1, the base line a and the base line c are located on the upper side of the substrate 1 and are parallel to each other, and the base line b and the base line d are located on the lower side of the substrate 1 and are parallel to each other. In addition, in the present embodiment, the signal transmission base line is printed on the substrate 1.

In this embodiment, the signal transmission conductors are printed on the slide 2.
