摘要： A planar reconfigurable antenna that is capable of generating omnidirectional and directional radiation patterns over a wide frequency band or over multiple frequency bands includes a substrate, one or more pairs of conductive elements on at least one side of the substrate, a common RF feed point, and respective switches that selectively connects one or all of the conductive elements to the common RF feed point. An omni-directional radiation pattern is generated when all of the conductive elements are connected to the common RF feed point, while a directional radiation pattern is generated when only a pair of conductive elements on opposite sides of the substrate are connected to the common RF feed point. In the directional radiation mode, the conductive elements that are not connected to the common RF feed point act as a reflector for other conductive elements that are connected to the common RF feed point.

摘要： The invention relates to a reconfigurable antenna system, which comprises a plurality of antenna units and does not employ phase shifters. Each antenna unit is by itself a reconfigurable antenna having at least an active radiating element which is coupled to one or more passive radiating elements. Each antenna unit is provided with one or more variable loads that can be electrically connected/disconnected to each other and with said antenna unit, to selectively configure the radiating properties of the system. A bias network is adopted to bias the variable loads and a control unit allows controlling the operation of said bias network. Each active radiating element is fed by at least a feeding line that provides it with a suitable polarization. Hence, the system can advantageously resort to multiple polarizations, each of them being provided by a same source. Preferably, each active radiating element receive its feeding signal from the source/s by means of power dividers and/or switches. Preferably, each antenna unit is covered by at least a radiating structure, comprising a plurality of passive radiating elements, which does not affect the reconfigurability of the antenna unit itself and increases the overall antenna gain. The antenna system is then characterized by remarkable beam-steering capabilities and high gain, avoiding the losses and complexities related to phase shifters and overcoming the typically small antenna gain values of current reconfigurable antenna systems.

摘要： Reconfigurable antennas in an ad-hoc network are provided where all nodes employ MIMO/SIMO/MISO communication techniques. Three types of reconfigurable antennas: Reconfigurable Printed Dipole Array (RPDA), Reconfigurable Circular Patch Antenna (RCPA) and Two-Port Reconfigurable CRLH Leaky Wave Antennas are used. The RPDA, RCPA and the CRLH Leaky Wave antennas have a different number of configurations as well as different degrees of pattern diversity between possible configurations. To effectively use these antennas in a network, the performance of centralized and decentralized antenna configuration selection schemes are quantified for reconfiguration at one or both link ends. The sum capacity of the network is used as a metric to quantify the performance of these antennas in measured and simulated network channels.

摘要： A method allows reconfigurable multi-element antennas to select the antenna configuration in MIMO, SIMO and MISO communication system. This selection scheme uses spatial correlation, channel reciprocal condition number, delay spread and average Signal to Noise Ratio (SNR) information to select the antenna radiation pattern at the receiver. Using this approach, it is possible to achieve capacity gains in a multi-element reconfigurable antenna system without modifying the data frame of a conventional wireless communication system. The capacity gain achievable with this configuration selection approach is calculated through numerical simulations using reconfigurable circular patch antennas at the receiver of a MIMO system that employs minimum mean square error receivers for channel estimation. Channel capacity and Bit Error Rate (BER) results show the improvement offered relative to a conventional antenna selection technique for reconfigurable MIMO systems.
