Abstract: This application provides a phase shifter and an electrically tunable antenna including the phase shifter, where the phase shifter includes a tuning accessory, and the tuning accessory includes a tuning portion for tuning input impedance of the phase shifter. One additional capacitance or inductance parameter is added in the phase shifter by using the tuning portion, to affect input impedance of a port, to further affect a port standing wave, thereby tuning the port standing wave by using the tuning accessory. In addition, the tuning accessory in this application is a molded part with a fixed structure.

Abstract: This disclosure provides an antenna. The antenna disclosure includes a reflective plate having a reflective surface, a mounting bracket, a feed network, and a radiating element. The mounting bracket is disposed on one side of the reflective surface, and the mounting bracket and the reflective surface form a cavity facing toward an exposure in a first direction. The feed network is disposed in the cavity. The feed network has a feed point, and a projection of the feed point is located in the exposure. The radiating element is disposed on the side of the reflective surface. A projection of the radiating element on the mounting bracket is located in the exposure, and the radiating element is coupled to the feed point. By the provided antenna disclosure material usage and an overall weight of the antenna can be reduced. This is conducive to improving communication quality of the antenna.
