Abstract
An antenna arrangement which includes two antennas which are resonant at a common operating frequency. The arrangement includes a circuit which combines output signals from each of the antennas to provide a combined signal output. Each antenna has an electrically insulative core of solid material having a relative dielectric constant greater than 5 and a three-dimensional antenna element structure. The structure includes at least a pair of elongate conductive antenna elements disposed on or adjacent a surface of the core.

An antenna arrangement for a portable terminal comprising:
- at least two antennas each resonant at a common operating frequency, and
- a circuit arranged to combine output signals from each of the said antennas at the said frequency to provide a combined signal output, wherein each antenna comprises:
- an electrically insulative core of a solid material having a relative dielectric constant greater than 5, and a three-dimensional antenna element structure including at least a pair of elongate conductive antenna elements disposed on or adjacent a surface of the core.
A portable clamshell terminal having a body portion and a cover portion hinged to the body portion, and a pair of dielectrically loaded helical antennas each resonant at a common operating frequency and each having a respective axis of symmetry, wherein the antennas are mounted in the region of the hinge axis and in a spaced apart side-by-side configuration with their axes parallel.
An antenna arrangement for a portable terminal, comprising:
- at least two antennas each resonant at a common operating frequency, and a circuit arranged to split an input signal into substantially identical split signals and to feed the split signals to each of the antennas, wherein each antenna comprises:
- an electrically insulative core of a solid material having a relative dielectric constant greater than 5, and a three-dimensional antenna element structure including at least a pair of elongate conductive antenna elements disposed on or adjacent a surface of the core.
