Abstract: A transmission line assembly includes a shielding cover and a signal line. The shielding cover is connected to a ground end. The shielding cover has an accommodation space. A first opening and a second opening are provided in the accommodation space. The signal line includes a first end and a second end that are disposed opposite to each other. The signal line penetrates the accommodation space, and there is a gap between the signal line and an inner side wall of the accommodation space. The first end passes through the first opening. The second end passes through the second opening. At least one of the first end and the second end of the signal line is configured to be connected to a signal end. The signal line is in an air dielectric, so that a signal loss is effectively reduced.

Abstract: Example multi-band antennas and communication devices are described. One example multi-band antenna includes a reflection plate and a feed structure. The reflection plate is provided with a slot, and the slot defines one strip conductor. One end of the strip conductor is connected to another part of the reflection plate. The feed structure includes a microstrip line used in a high-frequency antenna element in the multi-band antenna, where the microstrip line is located on one side of the reflection plate, and at least a part of a projection of the microstrip line on the reflection plate falls within a contour range of the strip conductor.

Abstract: Embodiments of this application disclose a common aperture antenna and a communication device. The common aperture antenna includes: a reflection panel and a low frequency antenna unit, a frequency selective panel, and a high frequency antenna unit that are disposed on the same side as the reflection panel and are arranged in sequence. In the direction perpendicular to the reflection panel, the distance between the high frequency antenna unit and the reflection panel is greater than the distance between the low frequency antenna unit and the reflection panel, the frequency selective panel is disposed between the high frequency antenna unit and the low frequency antenna unit, and the frequency selective panel is a reflection ground of the high frequency antenna unit and has a total reflection characteristic for the working frequency of the high frequency antenna unit.

Abstract: This application discloses an antenna, an antenna array, and a communications device. The antenna includes a radiation part and a feeding part. The feeding part is coupled to the radiation part and is configured to feed power to the radiation part, so that the radiation part radiates a low-frequency signal outward. The radiation part includes one or more frequency selection units with a bandpass characteristic, and the radiation part is a structure that is capable of exciting, when a high-frequency signal passes through, coupling currents. When the high-frequency signal passes through the radiation part, each pair of coupling currents excited on the radiation part appear in pairs and can cancel each other. This can reduce or even completely eliminate a high-frequency induced current with the same frequency as the high-frequency signal on the radiation part.
