Compact radiating array for wireless handheld or portable devices
A radiating system transmits and receives in first and second frequency regions and includes a radiating structure comprising first and second radiation boosters having maximum sizes smaller than 1/30 times the free-space wavelength of the lowest frequencies of the first and second frequency regions, respectively. The radiating system further includes a radiofrequency system having first and second ports respectively connected to first and second internal ports of the radiating structure, and a third port connected to an external port of the radiating system. 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.
