摘要： A multi-band antenna with improved antenna efficiency across a broad range of operative frequency bands with reduced physical size is described. The multi-band antenna includes a modified monopole element coupled to multiple antenna loading elements variably selectable to tune to one of a plurality of resonant frequencies. In one exemplary embodiment, the modified monopole element has a geometry other than that of a traditional monopole element and includes a switch array disposed between the modified monopole element and the multiple antenna loading elements and configured to couple a selected one or more of the antenna loading elements to the modified monopole element when tuning to a desired one of the plurality of resonant frequencies. The multi-band antenna resonant frequency is controlled by a wireless communication device selecting among the multiple antenna loading elements for tuning the multi-band antenna between operative frequency bands.

摘要： A radio frequency identification (RFID) system with a parasitic element to improve coverage and increase reading distance of RFID tags is disclosed. The parasitic element may be a loop of a conductive ma¬ terial and is not physically connected to any circuit. One or more RFID tags may be located within a predetermined distance of the parasitic element. The parasitic element receives a first signal from an RFID reader and re-radiates the first signal. The re-radiation improves the coverage of the RFID system. An RFID tag receives the re-radiated first signal from the parasitic element and, in response, transmits a second signal. The parasitic element receives the second signal from the RFID tag and re-radiates the second signal. The RFID reader receives the re-radiated second signal from the parasitic element and reads the information sent in the second signal by the RFID tag.

摘要： Aspects of the disclosure relate to a controllable reflective surface (e.g., reconfigurable intelligent surfaces (RIS) ) that reflects in multiple directions simultaneously. The controllable reflective surface may include an array of reflecting elements, each reflecting element comprising a radiating component and a phase-shifting component. The array of reflecting elements may be configured to receive control signal sets, where each control signal set configures the array of reflecting elements into a reflecting configuration having a plurality of subsets of the reflecting elements. Here, each subset of the plurality of subsets is configured to reflect radio frequency (RF) signals in a respective direction different from other ones of the first plurality of subsets. The reflecting configuration may define, for example, a block-wise configuration, and interlaced configuration, or a hybrid configuration of the plurality of subsets. Other aspects, embodiments, and features are also claimed and described.
