Broadband antenna

摘要

A broadband antenna for a wireless communication device includes a grounding unit for grounding; a first radiating element; a second radiating element electrically connected to the grounding unit; a signal feed-in element for transmitting a radio signal to the first radiating element in order to emit the radio signal via the first radiating element; and a passive component comprising an inductor, where the passive component is electrically connected between the first and the second radiating elements to work in conjunction with the first radiating element, the second radiating element and the grounding unit to form a loop antenna effect.

1. A broadband antenna for a wireless communication device, comprising:
a grounding unit, for providing ground; a first radiating element; a second radiating element, electrically connected to the grounding unit; a signal feed-in element, for transmitting a radio signal to the first radiating element in order to emit the radio signal via the first radiating element; and a passive component, comprising an inductor, wherein the passive component is electrically connected between a metal part of the first radiating element and the second radiating element to work in conjunction with the first radiating element, the second radiating element, and the grounding unit to form a loop antenna effect; wherein the metal part comprises a third radiating element, electrically connected to the first radiating element, wherein a second coupling gap exists between the third radiating element and the second radiating element such that the radio signal is fed into the third radiating element from the second radiating element by coupling; wherein the metal part further comprises a fourth radiating element, electrically connected to the third radiating element, wherein the fourth radiating element extends toward the same direction as the first radiating element.
