Abstract:
1. A broadband antenna, comprising: a coupling loop, having a first feed-in terminal and a second feed-in terminal; a first radiation body, being a main body and forming a first resonance loop with the coupling loop; and a second radiation body, comprising two L-shaped bodies respectively and symmetrically connected to the main body at distances away from ends of the main body as branches and forming a second resonance loop with the coupling loop; wherein the first resonance loop provides a first resonance frequency of the broadband antenna, and the second resonance loop provides a second resonance frequency of the broadband antenna; wherein the coupling loop feeds in signals according to the first resonance frequency and the second resonance frequency; wherein the coupling loop is separated from the first radiation body and the second radiation body.
