Slim Booster Bars for Electronic Devices

摘要

A wireless device includes at least one slim radiating system having a slim radiating structure and a radio-frequency system. The slim radiating structure includes one or more booster bars. The booster bar has slim width and height factors that facilitate its integration within the wireless device and the excitation of a resonant mode in the ground plane layer, and has a location factor that enables it to achieve the most favorable radio-frequency performance for the available space to allocate the booster bar. The at least one slim radiating system may be configured to transmit and receive electromagnetic wave signals in one or more frequency regions of the electromagnetic spectrum.

1. A wireless handheld or portable electronic device comprising:
a slim radiating system configured to transmit and receive electromagnetic wave signals in a first frequency region, the slim radiating system comprising:
a slim radiating structure comprising a ground plane layer and a first booster bar comprising a single standard layer of dielectric material including electrically connected top and bottom conductive surfaces, the first booster bar having a slim width factor greater than 3 and a slim height factor greater than 3 and being separated from the ground plane layer by a gap and having a location factor in a range of 0.3 to 1.8, wherein the first booster bar fits in an imaginary sphere having a diameter smaller than ⅓ of a radiansphere having a radius equal to a free-space wavelength corresponding to a lowest frequency of the first frequency region divided by two times π (pi);a first external conductive path;a radio-frequency system comprising a first matching circuit configured to provide impedance matching within the first frequency region at the first external conductive path; anda first internal conductive path coupling the first booster bar to the radio-frequency system.
