    摘要： Multiple input multiple output (MIMO) systems are able to provide wireless communications at increased data rates. These systems involve using a plurality of antennas on both the transmitter and receiver and the problem of how to accommodate such structures in user terminals, which are often required to be hand held then arises. An antenna arrangement which is suitable for MIMO communications and which can be incorporated into a user terminal such as a personal digital assistant (PDA) is described. A pair of co-polarised umbrella monopoles and a slot antenna are incorporated into a flap which extends at approximately 90° to the body of the PDA. A fourth monopole is mounted and protrudes from the PDA itself.

    摘要： Previous MIMO systems have used spatially diverse antenna elements in order not to reduce the number of orthogonal channels that can be realized. The present invention recognizes that this leads to large antenna sizes, as compared to multiple beam antenna systems which use closely spaced antenna elements. In order to provide a compact antenna unit, while still allowing a MIMO system to be exploited, the present invention recognizes that polarization diversity only can be used in a MIMO system without the need for spatially diverse antenna elements. Closely spaced antenna elements are used and this enables a compact MIMO antenna unit to be provided. In addition, such MIMO systems with polarization diversity but no spatial diversity can advantageously be used in line of sight situations and also combined with multi-beam antenna systems to further increase capacity.

    摘要： The present invention relates to a multi-band cellular basestation and in particular relates to antennas for such basestations. There is a growing need for mult-band basestation antennas for mobile communication systems, to serve existing 2nd generation systems, and emerging third generation systems. For example, GSM and DCS1800 systems currently coexist in Europe, and emerging 3rd generation systems (UMTS) will initially have to operate in parallel with these systems. The present invention provides a dual/triple/multi-band performance cellular basestation antenna having a shared aperature, having a first set of radiating elements operable at a first frequency range; a second set of radiating elements operable at a second frequency range; wherein the first set and second set of radiating elements are arranged in an interleaved fashion.
