The present invention discloses a dual-mode terminal antenna, which includes main antennas, auxiliary antennas and an antenna support. The main antennas comprise a first mode main antenna and a second mode main antenna, and the auxiliary antennas comprise a first mode auxiliary antenna and a second mode auxiliary antenna. The main antennas and the auxiliary antennas are fixed on the same antenna support, and spring leaves are set on each of the main and auxiliary antennas respectively. When the antenna support clasps a main board, four spring leaves of the main and auxiliary antennas touch four antenna feeding points on the main board respectively. An LC resonant circuit is set in front of each antenna feeding point, and each of the four LC resonant circuits respectively resonates on the operation band of the antenna corresponding to the antenna feeding point to which each of the four LC resonant circuits connects. The present invention also discloses a signal processing method, which solves the problem of signal interference and loss when antennas are in a reception mode in the prior art, through the high impedance of the LC resonant circuit to signals on different frequency bands. Further, the dual-band terminal antenna of the present invention simplifies the layout of a printed circuit board (PCB). |
