Abstract
An antenna for receiving and/or transmitting radio frequency (RF) signals at multiple cellular frequency bands is disposed on a non-conductive pane. The antenna includes a first antenna element and a second antenna element. The first antenna element has a first radiating element and a second radiating element arranged together in an opposing relationship to form a first bowtie shape. The second antenna element is spaced from the first antenna element and has 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 the first bowtie shape. A first trace element connects to and extends between said first and third radiating elements and a second trace element connects to and extends between said second and fourth radiating elements. The antenna establishes an electromagnetic coupling for dual band operation at the multiple cellular frequency bands.
