Abstract

A broadband antenna comprises a grounding component electrically connected to one grounding end, a feed-in source used for receiving a wireless signal, a first radiating body, a second radiating part, a conductive component, a second radiating body and a third radiating part, wherein the first radiating body comprises a first radiating part extending in the first direction, the second radiating part is extended in the opposite direction of the first direction, the conductive component is extended in the second direction, the second radiating body comprises a short circuit component electrically connected with the grounding component, the third radiating part comprises a subsection which keeps a first distance with the conductive component, and the first distance makes the third radiating part and the conductive component generate a coupling connecting effect, wherein the average perpendicular distance from the second radiating body to the grounding component is smaller than that from the first radiating part to the grounding component.

Description

technical field [0001] The invention refers to a broadband antenna, especially a broadband antenna utilizing the vertical coupling connection effect. Background technique [0002] Electronic products with wireless communication functions, such as notebook computers, personal digital assistants (PDA), etc., transmit or receive radio waves through antennas to transmit or exchange radio signals, and then access wireless networks. Therefore, in order to allow users to access wireless communication networks more conveniently, the bandwidth of an ideal antenna should be increased as much as possible within the allowable range, while the size should be reduced as much as possible to match the trend of shrinking electronic products. [0003] In the prior art, such as China Taiwan Patent No. I318022, a multi-frequency antenna 10 for wireless transmission has been disclosed, such as figure 1 shown. The multi-frequency antenna 10 includes a grounding part 100, a first radiating part ...
