A communication device includes a nonconductive housing, a cable, an antenna structure, and a signal source. The nonconductive housing has a hollow structure. The cable is coupled to the signal source. The cable includes a signaling conductor and a grounding conductor. The antenna structure includes an antenna body and an enclosed radiation element. The antenna body is coupled to the signaling conductor. The antenna body is disposed outside the nonconductive housing. The enclosed radiation element is coupled to the grounding conductor. The enclosed radiation element is disposed inside the nonconductive housing.

Communication device and antenna structure

An antenna structure includes a ground plane, a dielectric substrate, a first radiation element, a second radiation element, a third radiation element, and a fourth radiation element. The first radiation element is coupled to a signal source. Both the third radiation element and the fourth radiation element are coupled between the first radiation element and the second radiation element. The third radiation element has a first notch and a second notch. The fourth radiation element has a third notch and a fourth notch. A loop structure is formed by the first radiation element, the second radiation element, the third radiation element, and the fourth radiation element. A fifth notch is formed between the first radiation element and the third radiation element. A sixth notch is formed between the first radiation element and the fourth radiation element.

Antenna structure

A broadband antenna includes a substrate; a grounding unit; a first radiating element, including a first segment and a second segment substantially perpendicular to each other, wherein the first segment is electrically connected to the grounding unit and the second segment extends toward a direction; a second radiating element, coupled to the first radiating element; a third radiating element having a terminal coupled to or electrically connected to the second radiating element and another terminal electrically connected to the grounding unit; and a signal feed-in element electrically connected to the third radiating element for transmitting or receiving a radio signal; where the first, the second and the third radiating elements are disposed on the substrate along the direction defined by an order of the first segment of the first radiating element, the second radiating element and the third radiating element.

Broadband antenna

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.
