Personal communications apparatus

Abstract

A personal communications apparatus, for example a cellular telephone handset, has an antenna diversity arrangement comprising first and second antennas (102A, 102B) arranged with their polarisation axes slanted with respect to the median plane of the handset body (218). By a suitable choice of inclination angles one of the antennas can be arranged to be substantially vertical in use, whether by right or left handed users, thereby improving received signal strength from a vertically polarised base station. The arrangement also enhances diversity operation, since the correlation between the field strengths received by the antennas is reduced by their relative orientation. When the apparatus is used in a system employing a Code Division Multiple Access (CDMA) techniques, the apparatus preferably includes a 2D Rake receiver for mitigating the effects of multipath fading and interference.
