Abstract:
A phase shifter, an antenna, and a base station are provided. The phase shifter in the present invention includes a feed unit, a tapping element, a conductor section, and a ground element, and the feed unit is electrically connected to the tapping element. The tapping element is electrically connected to the ground element when being shifted by a preset angle by using a port of the conductor section as a start position, so that a transmit signal is reflected to an input port of the feed unit, and whether a cable is correctly connected is determined according to the signal of the input port, thereby signal transmission accuracy of an antenna is ensured.

Claim (Index 13):
A base station, comprising: an antenna, a radio remote unit (RRU), and a baseband processing unit (BBU, wherein:\n the antenna comprises multiple phase shifters and multiple radiating elements, wherein each phase shifter comprises a feed unit, at least one tapping element, at least one conductor section, and a ground element, wherein the feed unit is electrically connected to a first tapping element of the at least one tapping element, and the at least one tapping element is electrically connected in sequence; the at least one conductor section is at least one concentric curved conductor section; each tapping element is electrically connected to one conductor section; and each tapping element is shifted, by using a circle center of the at least one conductor section as a rotation axis, along the conductor section connected to each tapping element, so as to change a phase of a signal that passes through the conductor section connected to each tapping element, and then output the signal by using an output port of the conductor section connected to each tapping element; when each tapping element is shifted by a preset angle by using an output port of the conductor section connected to each tapping element as a start position, one tapping element is electrically connected to the ground element, so that a signal transmitted by the tapping element is reflected to an input port of the feed unit, a standing wave is generated by the signal of the input port, and then whether a cable of the input port is correctly connected is determined according to the signal of the input port; an output port of each phase shifter is connected to one radiating element; and an input port of each phase shifter is connected to the RRU; and the RRU is connected to the BBU.
