  • Patent number: 10547109
    Abstract: A radiating system comprises a radiating structure including two or more radiation boosters for transmission and reception of electromagnetic wave signals, a radiofrequency system and an external port. The radiating system is capable of operation in at least a first and second frequency regions which are preferably separated. The radiofrequency system comprises two or more matching networks and a combining structure at which, in transmission, electromagnetic wave signals from the external port are substantially separated and coupled to each radiation booster based on the frequency of the signals; and, in reception, signals from each radiation booster are combined and coupled to the external port. The radiofrequency system provides impedance matching to the radiating structure in the first and second frequency regions at the external port. An advantage of such radiating system is that signals from the first and second frequency regions are fed to and retrieved in one single port.

  • Publication number: 20140159982
    Abstract: A reconfigurable monopole antenna is described which includes a radiator element coupled to a feed point through at least two different current paths. The current paths are of different lengths to accommodate different frequency bands. To change the current paths, a feed-point switch is positioned at the antenna feed point for selectively supplying current along either a first current path or a second current path. The current paths share a majority of the radiator element so that separate radiator elements need not be used.
