摘要： An antenna has multiple antenna elements, with a beam forming Butler matrix, having antenna ports and input/output ports, with each of said antenna elements being connected to a respective port of the beam forming Butler matrix. Transceiver circuitry is connected to each of the input/output ports of the beam forming matrix by means of respective distinct transmit and receive paths and a respective duplexer. Individually controllable gain control elements are located in each of the transmit and receive paths. These can be controlled in response to signal strength measurements made by the antenna.

摘要： An antenna arrangement 10 comprises a loop of conductive material 14 spaced from a reflector 12 by solid dielectric spacer means 16 which defines a cavity located inside the loop 14. The dielectric spacer means 16 may be in the form of a circular, square or rectangular cylinder. The loop 14 may be a conductive layer which covers the end surface of the cylindrical dielectric spacer 16. A feed for the loop 14 may comprise two feed loops 18, 20 which are formed on the inner surface 22, 28 of the dielectric spacer defining the cavity. The feed loops 18, 20 may be arranged with a portion which is adjacent to the loop 14 such that signals are electromagnetically coupled between the feeds 18, 20 and the loop 14. Another antenna or antenna related circuitry 34 - 42 may be located within the cavity. A number of antennas may be arranged to form an antenna array. The antenna arrangement may provide a compact circular polarised antenna with a good bandwidth which may be used in a global positioning system (GPS).

摘要： A solid dielectric resonator antenna comprises a block of solid dielectric material 14, 40, mounted on a generally planar substrate 12, 42. The solid dielectric material has a dielectric constant in the range from 10-90. The cross-sectional area of the block of solid dielectric material in a plane parallel to the plane of the substrate increases, either linearly or in a stepwise manner, with increasing distance from the substrate. The block of solid dielectric material 14, 40 may be a single body or it may be made up differently-sized individual blocks or discs. The antenna may form part of an array of similar antennae (fig. 5).

摘要： A localization scheme and method using a laser sensor for indoor wheeled mobile robots (IWMR), which need to localize themselves for working autonomously, is provided. In this method, a laser sensor moves inside an onboard guide way and its distance measurements are used to robustly detect and recognize a unique target based on edge detection and pattern recognition techniques. From the distance measurements with respect to the recognized target, a kinematic model is developed to determine the IWMR orientation and location in the global co-ordinates (in 2-D). Such target recognition and localization methods are validated with experimental results.

The access point has a plurality of possible antenna beam directions. An available data rate is determining for each of the plurality of possible antenna beam directions; and a beam direction is selected based on the available data rates. The user is presented with an opportunity to select a data transfer direction, and the available data rate is determined for each of the plurality of possible antenna beam directions for the received one or more selected data transfer direction. The user is presented with an opportunity to select a beam direction selection criterion, such as a maximum available data rate, a minimum available data rate, and an average available data rate, and the beam direction is selected based on the received one or more selected beam direction selection criterion. The step of determining the available data rate for each of the plurality of possible antenna beam directions comprises, for each of the beam directions: establishing a connection with a remote site; waiting for a predetermined time period; and after expiry of the predetermined time period, measuring the available data rate. The user is presented with an opportunity to select a throughput test time, and the available data rate is determined at the selected throughput test time.

摘要： A duplexerless homodyne receiver, suitable for use in a base station of a mobile communications system, is described. Received signals are supplied to a wideband filter, and the filtered signals are supplied to a first low noise amplifier. The amplified signals are supplied to a first narrowband filter. These filtered signals are supplied to a second low noise amplifier, and the further amplified signals are supplied to a second narrowband filter. These signals, at the received radio frequency are then supplied to a quadrature demodulator, for direct downconversion to baseband. This combination of two low noise amplifiers and two narrowband filters provides the required attenuation of the interferer to avoid saturating the subsequent quadrature demodulator, while also providing enough gain to ensure that the noise figure of the received signal is not degraded. This arrangement allows these requirements to be met, while using components which are smaller and cheaper than would be the case in attempting to meet the requirements using just one amplifier and one filter.
摘要翻译：描述适用于移动通信系统的基站中的无双工器的零差接收机。接收的信号被提供给宽带滤波器，滤波后的信号被提供给第一低噪声放大器。放大的信号被提供给第一窄带滤波器。这些滤波信号被提供给第二低噪声放大器，并且进一步放大的信号被提供给第二窄带滤波器。然后，将所接收的射频的这些信号提供给正交解调器，用于直接下变频到基带。两个低噪声放大器和两个窄带滤波器的组合提供干扰源的所需衰减，以避免后续正交解调器饱和，同时还提供足够的增益以确保接收信号的噪声系数不会降低。这种布置允许满足这些要求，同时使用比尝试仅使用一个放大器和一个滤波器来满足要求的情况更小和更便宜的部件。
