A multi-band antenna for a portable communication device is disclosed, in which the communication device includes a first housing, a second housing and a substrate. The multi-band antenna includes a feeding portion, a system ground plane, a metal ring, a resonant cavity, a first and a second radiating portion. The system ground plane is disposed on the substrate. The metal ring is connected to the first housing, and forms a space with the first housing to accommodate the substrate, in which the metal ring is electrically coupled to the system ground plane through a plurality of ground ends. The resonant cavity is formed between the system ground plane and the metal ring to generate a first resonant mode. The first and the second radiating portion are disposed on the second housing, for generating a second and a third resonant mode, respectively.

Multi-band antenna for portable communication device

A multi-band antenna includes a feed-in section, a loop conductor, a first conductor arm, a second conductor arm, and a third conductor arm. The feed-in section includes a feed-in point for feeding of signals. The loop conductor extends from the feed-in section and has a grounding point disposed adjacent to the feed-in point. The first conductor arm is configured to resonate in a first frequency band and extends from the feed-in section. The second conductor arm is configured to resonate in a second frequency band and extends from the feed-in section. The third conductor arm is configured to resonate in a third frequency band and extends from the feed-in section. At least one of the loop conductor, the first conductor arm, the second conductor arm, and the third conductor arm is bent so as to be disposed in different planes.

Multi-band antenna

A multi-band antenna includes a loop conductor, a first conductor arm, and a second conductor arm. The loop conductor is configured to resonate in a first frequency band and includes a feed-in end for feeding of signals and a main body that extends from the feed-in end, and that has a grounding point disposed adjacent to the feed-in end. The first conductor arm is configured to resonate in a second frequency band and extends from the feed-in end. The second conductor arm is configured to resonate in a third frequency band and extends from the feed-in end. At least one of the loop conductor, the first conductor arm, and the second conductor arm is bent so as to be disposed in different planes.

A multi-band antenna module is disposed in a housing of an electronic device. The housing has a grounding plane disposed therein and includes a metal frame part having two ends electrically connected to opposite side edges of the grounding plane. The multi-band antenna module includes a conductor, a substrate, a grounding section, and a first radiator section. The conductor is to be coupled across the metal frame part and the grounding plane so as to cooperate with the grounding plane and a portion of the metal frame part to form a closed loop thereamong, in which the substrate is disposed. The first radiator section and the grounding section are disposed on the substrate, with the grounding section to be coupled electrically to the grounding plane. A portion of the first radiator section is disposed to cooperate with the closed loop to resonate in a first frequency band. Another portion of the first radiator section is disposed to cooperate with the grounding section to resonate in a second frequency band.
