Abstract

The present invention provides a multi-band wideband antenna comprising of the first radiation body, the second radiation body, the third radiation body, grounding plane and multiple short elements. The first radiation body excites the first resonance mode to make multi-band wideband antenna having high band wideband frequency width. The second radiation body excites the second resonance mode to make multi-band wideband antenna having middle band wideband frequency width. The third radiation body excites the third resonance mode to make multi-band wideband antenna having low band wideband frequency width. Multiple short elements couples the first radiation body, the second radiation body and the third radiation body to grounding plane. Wherein, the radiation field type of the first resonance mode, the second resonance mode and the third resonance mode are not disturbed for each other.

Description

technical field [0001] The present invention relates to a multi-band broadband antenna and a hand-held electronic device using the same, and in particular to a multi-band broadband antenna resonating multiple wide-bands on a single conductor structure and a hand-held electronic device using the same. Background technique [0002] Generally, when an antenna is in operation, an antenna diversity (Antenna Diversity) architecture is usually used to solve the problem of multi-path (Multi-path) interference. When the radio frequency system adopts multi-band operation, most of the antennas adopt multiple sets of independent antennas or compound antennas to achieve the purpose of antenna diversity. However, this would significantly increase system complexity and reduce operational reliability. Therefore, the traditional multi-band antenna uses the frequency doubling effect of the resonant structure to excite multiple groups of resonant modes to achieve multi-band operation. [000...
