摘要： A radiating system for transmitting and receiving signals in first and second frequency regions includes a radiating structure, a radiofrequency system, and an external port. The radiating structure has first and second isolated radiation boosters coupled to a ground plane layer. A first internal port of the radiating structure is between the first radiation booster and the ground plane layer, and a second internal port is between the second radiation booster and the ground plane layer. A distance between the two internal ports is less than 0.06 times a wavelength of the lowest frequency. The maximum size of the first and second radiation boosters is smaller than 1/30 times the wavelength of the lowest frequency. The radiofrequency system includes two ports connected respectively to the first and the second internal ports of the radiating structure, and a port connected to the external port of the radiating system.

摘要： 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.

摘要： A wireless handheld device comprises an internal antenna system that operates in first and second non-overlapping frequency bands with respective bandwidths. The antenna system includes: a ground plane; first and second antenna elements connected to a common input/output port, wherein a bandwidth of each of the antenna elements is less than at least one of the first and second operating frequency bandwidths and less than a frequency bandwidth for the antenna system; a combining structure to couple first and second signal transmission paths from the antenna elements to the common input/output port; and a phase shifting element on the first signal transmission path that imparts a phase delay to signals on the first signal transmission path. The phase delay minimizes a sum of reflection coefficients of the antenna elements to cause the frequency bandwidth for the antenna system to include at least the first and second operating frequency bands.
