Abstract
An antenna is integrated with a window of a vehicle primarily for operating in multiple cellular telephone frequency bands. The antenna includes a conductive area formed of conductive material defining a slot. The slot is dimensioned such that edges adjacent the slot radiate primarily in a first frequency band. The antenna also includes a conductive strip formed of conductive material extending from the conductive area. The conductive strip is dimensioned to radiate primarily in a second frequency band.
