<p>A radio communication receiver 20 includes an antenna array having at least two antennas 24, 25 to provide antenna diversity. The receiver 27 is for receiving signals containing orthogonally coded data sub-streams derived from a source data stream. The receiver 27 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 24, 25 has an electrically insulating core of solid material having a dielectric constant greater than 5. Each antenna 24, 25 also has a three-dimensional antenna element structure disposed on or adjacent the outer surface of the core. The coded data may be formed using orthogonal frequency division multiple access OFDMA or code division multiple access CDMA techniques. The polar diversity of the dielectrically loaded antennas 24, 25 may allow a compact arrangement for a PCMCIA device suitable for MIMO communication.</p> |
