An antenna device includes a main body. The main body has a first radiator which has a first radiating portion, a third radiating portion, a second radiating portion connected with the first radiating portion and the third radiating portion to show a door shape, a fourth radiating portion extended outwards from the third radiating portion, and a fifth radiating portion extended downwardly from the third radiating portion, and stretched towards the same side of the third radiating portion as the second radiating portion, and a second radiator extended toward the third radiating portion from the first radiating portion. A feeding portion and a grounding portion are extended downwards from the second radiator side by side. A resonance element has an elongated first resonating portion spaced from the main body, and a second resonating portion extended perpendicularly from an end of the first resonating portion away from the main body.

An antenna structure includes a low frequency radiator, a high frequency radiator, and a connecting element. The connecting element has a rear end and a front end opposite to the rear end. A feeding element and a grounding element are extended from the front end of the connecting element and arranged adjacent to each other. The low frequency radiator includes a substantially inverted-L shaped first radiating part extended from the rear end of the connecting element, a meander-like second radiating part extended frontward from a front end of the first radiating part, and a substantially lying U-shaped third radiating part with a rearward opening extended from a free end of the second radiating part. The high frequency radiator includes a first extension piece extended frontward from the front end of the connecting element and located under the second radiating part with space.

An antenna system adapted for a communication device has a common antenna with a predetermined length, an AM matching circuit matching with the common antenna and an FM matching circuit matching with the common antenna. A switch alternatively electrically connects the common antenna to the AM matching circuit and the FM matching circuit for achieving the AM function and FM function.

An antenna connected with a matching circuit is mounted in a portable electronic device for receiving radio frequency band. The antenna includes a flat-plate coil with a shape thereof depending on a receiving space of the portable electronic device, a feeding portion defined at one free end of the coil for connecting with the matching circuit, and a grounding portion defined at the other free end of the coil. Accordingly, the antenna can be received in the portable electronic device with a small-occupied space, and is convenient for a user to listen to broadcast at random.

A wireless device includes a housing having a shielding case and a dielectric case. The housing receives a printed circuit board and an antenna element. The printed circuit board has a feeding pad, a first ground pad and a second ground pad. The antenna has a feeding portion electronically coupled with the feeding pad of the printed circuit board and a ground portion electronically coupled with the shielding case for increasing ground dimension to improve antenna characteristic. The first and second ground pads of the printed circuit board electronically coupled with the shielding case for reducing coupling effect to improve antenna characteristic.

A reusable substrate structure and a method of handling the reusable substrate are disclosed. The reusable substrate structure comprises a substrate, at least one epitaxial layer and at least one inter layer. The method used in this invention is by employing a separating method in order to decompose the inter layer. Since the inter layer is decomposed, the substrate and the epitaxial layer will be separated. This achieves the goal of reusable substrate and then can save the material cost without additional wasting.

An integrated multi-band antenna has a first radiating conductor, a second radiating conductor spaced from the first radiating conductor, a trap element connected to the first and second radiating conductors, a third radiating conductor with a first feeding point connected to the first radiating conductor, a fourth radiating conductor connected to the second and third radiating conductors, a meandering radiating conductor having two ends which respectively connect a fifth radiating conductor with a second radiating conductor and a sixth radiating conductor parallel to the meandering radiating conductor and a ground portion arranged close to the first radiating conductor and spaced from the fifth radiating conductor. The second, third and fourth radiating conductors resonate at a first frequency bandwidth. The first, second and third radiating conductor and the trap element resonate a second frequency bandwidth. The fifth, sixth and meandering radiating conductors resonate a third and a fourth frequency bandwidths.
