Abstract
A phase shifter and a wireless communication device are provided. The phase shifter includes a first substrate, a radio frequency transmission line arranged on a side of the first substrate, and a bias line connected to the radio frequency transmission line. The bias line includes a first wire and a second wire. A sheet resistance of the second wire is greater than a sheet resistance of the radio frequency transmission line. The first wire and the radio frequency transmission line are connected and form an integrated structure. A line width of the first wire is less than a line width of the radio frequency transmission line. The second wire and the first wire form a lapping region in an extension direction of the first wire. In the lapping region, the second wire is arranged on a side of the first wire away from the first substrate.
