Concentrated Wireless Device Providing Operability in Multiple Frequency Regions

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.
