Abstract: The present invention discloses a multi-frequency antenna, which comprises a radiation conductor, a parasitic conductor, a feeder cable and a ground plane. The radiation conductor comprises a feeder member, a first radiation arm and a second radiation arm. The feeder cable comprises a central cable and an outer cable. The feeder member has a coupling side. The parasitic conductor is connected with the ground plane and has a coupling side arranged along the contour of the coupling side of the feeder member. The coupling side of the parasitic conductor and the coupling side of the feeder member have a gap there between. The first and second radiation arms excite a low-frequency resonant mode, and the parasitic conductor excites a high-frequency mode. Therefore, the multi-frequency antenna of the present invention not only covers several operational frequency bands and has a UWB feature, but also has a simplified structure.

Abstract: The present invention discloses a multi-antenna integration module, which comprises a first antenna, a second antenna and a common unit. The first antenna further comprises a first feeder cable, a first feeder member, a coupling unit, which has a first and second coupling members, and an extension conductor. The second antenna further comprises a second feeder cable, a radiation conductor and a coupling conductor. The common unit further comprises a common conductor which has a first and second conductor, a common short-circuit member and a common ground member. In the present invention, the design of the common unit integrates the radiation conductors, short-circuit members and ground members of different antenna systems into a single structure, whereby the isolation effect is promoted, and the signal interference among different antennae is decreased, and the space occupied by the antenna layout is reduced.

Abstract: An antenna module is provided. The antenna module comprises a first radiation conductor, a second radiation conductor, a short-circuit element (s/c element), a ground plane, a feed-in cable and a spurious radiation conductor. One terminal of the second radiation conductor is near the first radiation conductor with a gap. One terminal of the s/c element is connected to the second radiation conductor and the other side of the s/c element is connected to the ground plane. The feed-in cable comprises a centre conductor and an external conductor, wherein the centre conductor is connected to the first radiation conductor and the external conductor is connected to the ground plane. The spurious radiation conductor is connected to the second radiation conductor. The second radiation conductor comprises a spurious radiation plate, a first radiation piece and a second radiation piece within the two sides of the second radiation conductor.

Abstract: A foldable electronic device comprising a first body, a second body, a second body, a pivot, an antenna module, and a coupling module is provided. The first body comprises a first cover. The second body comprises a second cover. The pivot allows the second body to rotate relative to the first body. The antenna module is disposed within the first body and comprises a ground plane electrically connected to the first cover. The coupling module comprises a first coupling portion and a second coupling portion. The first coupling portion is disposed within the first body and electrically connected to the first cover. The first coupling portion is adjacent to the antenna module, and a gap formed between the antenna module and the first coupling portion. The second coupling portion disposed within the second body is electrically connected to the second cover and corresponds to the first coupling portion.

Abstract: A coupling antenna has a ground plane, a main radiating assembly and a secondary radiating assembly. The main radiating assembly is mounted on the ground plane and has a substrate, a feeding-and-coupling assembly and a shorting member. The feeding-and-coupling assembly has a feeding member, a coupling member and an extension member. The second radiating assembly is mounted on the ground plane, is connected to the main radiating assembly and has a first radiating patch and a second radiating patch. With the extension member and the first and second radiating patches, operating bandwidth of the coupling antenna is improved.
