Radio communication system
First Claim
1. A radio communication receiver device for operation at one or more frequencies in excess of 200 MHz for receiving a plurality of signals containing orthogonally coded data sub-streams derived from a source data stream, wherein the device comprises an antenna array having at least two antennas to provide antenna diversity, and, coupled to the antenna array, receiver circuitry having a detection stage arranged to detect the data sub-streams and a combiner stage for combining the detected data sub-streams to recover the source data stream, and wherein each of the antennas comprises:
- an electrically insulative core of solid material having a relative dielectric constant greater than 5, and a three-dimensional antenna element structure disposed on or adjacent the outer surface of the core and defining an interior volume, the material of the core occupying the major part of the said interior volume.

Abstract
A radio communication receiver which includes an antenna array having at least two antennas to provide antenna diversity. The receiver is for receiving signals containing orthogonally coded data sub-streams derived from a source data stream. The receiver also has receiver circuitry, coupled to the antenna array, having a detection stage to detect the data sub-streams and a combiner stage for combining the detected data sub-streams to recover the source data stream. Each antenna has an electrically insulative core of solid material having a dielectric constant greater than 5. Each antenna also has a three-dimensional antenna element structure disposed on or adjacent the outer surface of the core.
