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： 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： An access point is adapted to allow access from at least one user device, and comprises radio frequency transceiver circuitry for communicating over a wireless link with a base station selected from a plurality of available base stations. 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 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.
