摘要： A wireless handheld or portable device includes a communication module with a MIMO system that provides multiband MIMO operation in first and second frequency bands. The MIMO system includes first and second radiating systems, a ground plane common to the two radiating systems, first and second radio frequency systems, and a MIMO module. The first and second radiating systems both operate in the first and second frequency bands and respectively include first and second radiating structures coupled to the ground plane, which respectively have first and second radiation boosters that fit in an imaginary sphere having a diameter smaller than ¼ of a diameter of a radiansphere of a longest wavelength of the first frequency band. The first and second radiofrequency systems respectively modify impedance of the first and second radiating structures to provide impedance matching to the first and second radiating systems within the first and second frequency bands.

The radiofrequency system includes: first and second reactance cancellation element providing impedances having an imaginary part close to zero for respective frequencies in the first and second frequency regions and a delay element interconnecting the first and second reactance cancellation elements to provide a difference in phase therebetween to produce first and second impedance loops in the first and second frequency region, respectively, at the external port.

摘要： A radiating system of a wireless device transmits and receives electromagnetic wave signals in a frequency region and comprises an external port, a radiating structure, and a radiofrequency system. The radiating structure includes: a ground plane layer with a connection point; a radiation booster with a connection point and being smaller than 1/30 of a free-space wavelength corresponding to a lowest frequency of the frequency region; and an internal port between the radiation booster connection point and the ground plane layer connection point. The radiofrequency system includes: a first port connected to the radiating structure's internal port; and a second port connected to the external port. An input impedance at radiating structure's disconnected internal port has a non-zero imaginary part across the frequency region. The radiofrequency system modifies impedance of the radiating structure to provide impedance matching to the radiating system within the frequency region at the external port.

摘要： A wireless handheld or portable device includes an antenna system operable in a first frequency region and a higher, second frequency region. The antenna system comprises an antenna structure, a matching and tuning system, and an external input/output (I/O) port. The antenna structure comprises at least one radiating element including a connection point, a ground plane layer including at least one connection point, and at least one internal I/O port. At least one radiating element of the antenna structure protrudes beyond the ground plane layer. The antenna structure features at any of its internal I/O ports when disconnected from the matching and tuning system an input return loss curve having a minimum at a frequency outside the first frequency region of the antenna system. The matching and tuning system modifies the impedance of the antenna structure and provides impedance matching to the antenna system in the first and second regions.
