The disclosed embodiments relate to the design of a system that implements a reflectarray antenna. The system includes a time-modulated metasurface, which is configured to act as a planar reflector for an electromagnetic wave that is radiated by a feeder into free space at an operation frequency f.sub.0. The time-modulated metasurface includes time-modulated unit-cells that provide a nonlinear conversion between f.sub.0 and another desired frequency f.sub.d. The system also includes a phase-delay mechanism, which adjusts a phase delay by acting on a phase applied to a modulation frequency f.sub.m that modulates each unit-cell. The nonlinear conversion and the phase-delay mechanism operate collectively to facilitate angle-independent nonreciprocity by imposing different phase gradients during up-conversion and down-conversion processes, and by preventing generation of certain propagative harmonics due to total internal reflection.

Embodiments of this application disclose an integrated circuit and a terminal device, to resolve a problem that an existing dual-band antenna has a relatively small low-frequency band range and is difficult to meet use requirements.

The first radiation patch, the second radiation patch, and the radio frequency processing chip are separately placed on different layers of the bearer structure. A first feed line and a second feed line are disposed in the bearer structure. The radio frequency processing chip feeds the first radiation patch by using the first feed line. The radio frequency processing chip feeds the second radiation patch by using the second feed line.
