Abstract:
1. A broadband mobile phone antenna, comprising; a parasitic antenna, including a main antenna and a matching circuit thereof; a first antenna switch connected with the main antenna and the matching circuit thereof, wherein the first antenna switch is further connected with a mobile phone base band chip and a mobile phone motherboard, and is used to perform frequency band switching of said main antenna; at least two second matching circuits; and a second antenna switch connected with the parasitic antenna and the at least two second matching circuits, and connected with the mobile phone base band chip, wherein said parasitic antenna is used to change a resonance frequency of the main antenna by coupling with said main antenna; said second antenna switch is controlled by a mobile phone base band chip, working on the same frequency band as that of said first antenna switch, and is used to perform switching of said parasitic antenna between said at least two second matching circuits; and said first antenna switch is a main antenna switch, and said second antenna switch is a parasitic antenna switch.
