Classification: CPC H | IPC H

Claim 5:
6. A terminal device, comprising the radio frequency circuit,
wherein the radio frequency circuit comprises:
a radio frequency module;
a first combiner;
a second combiner;
a main antenna, directly connected to the first combiner; and
a secondary antenna, directly connected to the second combiner;
wherein the main antenna is connected to the radio frequency module through the first combiner, and
the secondary antenna is connected to the radio frequency module through the second combiner; and
wherein the first combiner and the second combiner both receive a main antenna signal of at least one frequency band and a secondary antenna signal of a corresponding frequency band; the radio frequency module transmits the main antenna signal to the main antenna via the first combiner and transmits the secondary antenna signal to the secondary antenna through the second combiner in an ordinary operation; and the radio frequency module transmits the main antenna signal to the secondary antenna via the second combiner and transmits the secondary antenna signal through the first combiner when a signal transmission of the main antenna is influenced.
