Abstract: A compressed antenna in a volume suitable for use in the front ends of small communications devices. The compressed antenna operates for exchanging energy in one or more bands of radiation frequencies. The antenna includes one or more radiation elements formed of segments electrically connected so as to exchange energy in one or more of the bands of the radiation frequencies. The radiation element has segments three-dimensionally arrayed and compressed in a volume.

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.

Abstract: A multi-band compressed loop antenna is formed of multiple, directly and/or indirectly connected, compressed loops for use in a communication device to exchange energy over multiple frequency bands of operation. Each loop is formed by multiple and numerous segments arrayed in multiple diverse directions which forms a compressed loop so that the area of the antenna is decreased by combining such compressed loops. The multiple loops provide for resonances in multiple discrete frequency bands of operation. The multiple loops are arrayed in different configurations that include nested (concentric) and non-nested (non-concentric) loops as well as closely located and separated loops on the same or different layers of single or multi-layer structures.
