Abstract:
1. A window having an integrated antenna for dual band operation at a first frequency band and a second frequency band, said window comprising: a nonconductive pane; a first antenna element disposed on said nonconductive pane and having a first radiating element and a second radiating element arranged together in an opposing relationship to form a first bowtie shape; a second antenna element disposed on said nonconductive pane and spaced from said first antenna element, said second antenna element having a third radiating element and a fourth radiating element arranged together in an opposing relationship to form a second bowtie shape with a different dimension than said first bowtie shape; and a first trace element connected to and extending between said first and third radiating elements and a second trace element connected to and extending between said second and fourth radiating elements, both of said trace elements establishing an electromagnetic coupling for said dual band operation.
