摘要： A MIMO antenna 10 comprises first 11 and second 12 spatially separated PIFA antenna elements arranged parallel to each other on an antenna planar platform 13 to radiate in substantially the same direction. The first 11 and second 12 PIFA elements comprise first 16a and second 16b antenna feeds arranged in respective planes. The feed planes are arranged to be perpendicular to each other, to mitigate mutual coupling. One or more parasitic radiators 18a, 18b may be included in the elements 11 and 12 and the elements 11, 12 may have rectangular or triangular, possibly with slots cut out, radiating top plates 14a, 14b and ground plates 15a, 15b. The elements 11 and 12 may be housed within a radome and used in or on a vehicle or formed into a body wearable garment. The MIMO antenna 10 is particularly suitable for use in compact, lightweight, rugged, efficient, broadband antenna designs.

摘要： A dual polarised omnidirectional antenna apparatus (20) capable of operating in transmit and receive, comprising at least two dual polarised directional antennas (21) configured to be mountable in a substantially equi-spaced distributed array around and pointing away from a platform, wherein the antenna apparatus (20) is configured such that, when operated in transmit, the dual polarised directional antennas operate in phase with each other to deliver a combined omnidirectional, dual polarised, performance. This increases operational bandwidth and mitigates interference effects in communications applications.

摘要： A method of active testing of wireless devices, such as mobile phone handsets, is disclosed. The wireless device 15 is located in a reverberation chamber 10 with a base station antenna 13. A reference signal 22 generated by a base station emulator 16 is transmitted from the base station antenna to the wireless device. Feedback data from the wireless device is obtained. This enables the performance of the wireless device in a given signal environment to be assessed. The feedback data is optionally reference signal received power (RSRP) or/and reference signal received quality (RSRQ) and may be transmitted wirelessly. A noise antenna 14 driven by a noise generator 18 is an optional feature which enables performance of the downlink to be measured in the presence of noise with a known signal to noise ratio.

摘要： A body-wearable antenna system is described that comprises at least two antenna elements (2, 4) arranged to be mountable in a substantially equi-spaced distributed array around a user's body. Each antenna element is a directional type antenna and the antenna system is configurable such that when worn the antenna elements operate in phase to deliver a combined, higher gain, omnidirectional performance radiating away from the user's body, compared to one or more conventional body-worn omnidirectional antennas. The antenna system can operate in transmit and receive. Each antenna element may be a planar inverted-F antenna (PIFA) housed in a protective radome (3, 5). Each PIFA may feature at least one slot cut into the radiating top plate or at least one parasitic radiator, or a combination of both, to allow operation within distinct frequency bands and with predetermined impedance bandwidth.

摘要： A directional antenna 300 comprises a planar antenna having a main radiating element 303 and a beam focussing module 305 for focussing the radiation along an antenna boresight. The beam focussing module comprises a parasitic beam focussing element 307, configured to resonate at the predetermined wavelength, and a means 306 for mounting the beam focussing element onto the antenna. The parasitic beam focussing element comprises a planar disc of electrically conductive material, and the means for mounting is arranged to hold the planar disc substantially parallel to and physically separated from the main radiating element, such that the beam focussing element can electromagnetically couple to the main radiating element at any polarisation. This focusses the beam around the antenna boresight at multiple polarisations. The beam focussing element may comprise a plurality of parasitic planar discs, which may be separated from each other and have a range of diameters. A base station antenna array (600, Figure 6) comprising a plurality of such directional antennas and a method of manufacturing such a directional antenna are also provided.

摘要： A method and apparatus for regenerating a signal is provided. The method involves sampling a received signal 13 to obtain a plurality of samples each having an associated magnitude. The samples are sorted to obtain a statistical distribution 15 which may be a histogram. Known distributions are fitted to the statistical distribution using a fitting operation 16, and for each a measure of similarity is obtained. A matched distribution is then determined from the measures of similarity, the matched distribution corresponding to an optimum value of the measure of similarity. A regenerated signal is then synthesised using the matched distribution and the regenerated signal is then output. Such a method purports to mitigate a storage burden associated with the recording and subsequent regeneration of representative wireless signal environments for wireless device testing.

摘要： A body-wearable antenna system 1 with at least two directional antenna elements 2 and 4 mountable in a equi-spaced distributed array around the user's body (e.g. back and front), wherein antenna elements operate in phase to deliver a combined omnidirectional performance radiating away from the user's body. Antenna elements 2 and 4 are respectively securely mounted within radomes 3 and 5 and worn on the front and back of the user. The antenna elements can be planar inverted F-shaped (PIFA) antennas and the radomes may be made from hard plastics. The PIFA antennas may have dual band capability by providing a slot in the radiating top plate of the PIFA and wide band frequency operation may be achieved by the use of parasitic resonators. Parts of the antennas may be made from flexible materials. Each antenna element is connected via a connector (not shown) to a coaxial cable 8 which electrically connects the antenna elements to a 2:1 zero degree phase power divider 7 which is connected to a power source held within equipment casing 6.

摘要： A vehicle antenna apparatus, including directional antenna elements arranged to be mountable in a distributed array around and pointing away from a vehicle, a powering means configured to power the directional antenna elements in phase with each other, and a method of use and manufacture of the same. The antenna apparatus further includes an omnidirectional antenna arranged to be mountable with the vehicle, with the powering means being further configured to power the omnidirectional antenna in-phase with the directional antenna elements. This provides a combined radiative performance radiating away from the vehicle suitable for communications applications.
