摘要： A multi-band antenna system for MIMO applications is adapted to provide high isolation between antennas across a wide range of frequencies. Multiple Isolated Magnetic Dipole (IMD) antennas are co-located and connected with a feed network that can include switches that adjust phase length for transmission lines connecting the antennas. Filtering is integrated into the feed network to improve rejection of unwanted frequencies. Filtering can also be implemented on the antenna structure. Either one or multi-port antennas can be used.

摘要： A Modal antenna system, control system, and algorithm is described which provides for improved connectivity in a communication system where statistics of previous antenna modes or beam positions for a mobile device operating in conjunction with specific base stations, access points, or other communication terminals are used to make intelligent decisions for current antenna beam state for optimal connectivity. A modal antenna is implemented to provide a variable radiation pattern for improved connectivity and an algorithm is provided that controls current beam position as the mobile device moves through a communication network.

摘要： A multi-function array is described where several communication system functions are realized using the same antenna architecture. An array of antenna elements where each antenna element can generate multiple radiation patterns is described; the multiple radiation patterns from each antenna element provides increased capability and flexibility in generating a phased array, a MIMO antenna system, a receive diversity antenna system, as well as direction finding feature by way of an interferometer function provided by one or multiple elements. The small volume attributes of the antenna elements populating the array lend this technique to mobile wireless devices as well as access points.

摘要： A spatial filter is developed for specific absorption rate (SAR) reduction in a wireless device. A conductive element is designed to modify the near field distribution of an antenna operating in a wireless device. This reduces SAR while minimizing degradation of antenna efficiency at one or several frequency bands that the antenna is designed to operate over. Lumped reactance can be designed into the conductive element to generate low pass, band pass, and/or high pass frequency characteristics. Distributed reactance can be designed into the conductive element to replace or to work in conjunction with the lumped reactance. Active components can be designed into the conductive element to provide dynamic tuning of the frequency response of the conductive element.
