Abstract
Directional antennae on aircraft and on cellular telephone base stations, having a polarity opposite that of potentially interfering ground system signals, minimize signal strength of air cellular signals received by ground cellular stations. Aircraft directional antennae comprise patch antennae or vertical arrays of loop elements or vertical arrays of virtual loop elements. Additionally, air cellular signals are switched to channels not currently in use by ground cellular systems.
