Abstract
A radio frequency device includes a feeding structure and a phase shifting structure. The feeding structure includes opposite first and second substrates, and a dielectric layer between the first and second substrates. The first substrate includes a coupling branch and a delay branch, which are respectively connected to two output terminals of a power divider, on an inner side of the first substrate. The second substrate includes a receiving electrode on its inner side, the receiving electrode and the coupling branch form a coupling structure, and their orthographic projections on the first substrate at least partially overlap each other. A length of an orthographic projection of both the coupling branch and the receiving electrode on the first substrate is different from a length of the delay branch. The phase shifting structure includes first and second transmission lines directly and electrically connected to the coupling branch and the delay branch, respectively.
