Abstract

A finely-tuned, compressed antenna in a cube with one or more frequency bands and with high isolation between bands. The antenna is suitable for use in the front end of small, hand-held communications devices. The antenna includes one or more radiation elements, each element for operating in one or more of the bands. A radiation element is formed of a plurality of sections formed of electrically conducting segments where the segments are electrically connected to exchange energy in one or more of the bands of the radiation frequencies. One or more of the radiation elements has segments arrayed in a compressed pattern where the compressed pattern extends in three dimensions to fill a cube.
