Disclosed are an adjustable phase shifting device for an array antenna and an antenna. The device comprises a feeder branching network, wherein the network contains transformer parts of different widths which are used for reducing the reflection of signals passing through the network; the network is coupled to an input port and an output port through one or more feeder nodes and parts, the input and output ports are arranged on a first edge of the device, a pull rod provided with a dielectric element is mounted on a second edge of the device, the dielectric element is mounted on the pull rod adjacent to the feeder parts and can move along the surfaces of the feeder parts, and a phase relationship between the dielectric element and the output port is synchronously adjusted; and the dielectric element contains one or more transformer parts which are used for reducing the reflection of the signals passing through the network, wherein two ends of the dielectric element adjacent to the feeder parts and connected to a first node of the input port are both provided with a transformer part, and other dielectric elements are merely provided with transformer parts at the end overlapping with some feeders. |
