An antenna structure includes a radiating element and an antenna radome. The antenna radome has at least one dielectric layer, which has an upper surface having many S-shaped metal patterns and a lower surface having many inverse S-shaped metal patterns corresponding to the S-shaped metal patterns. The S-shaped metal patterns are respectively coupled to the corresponding inverse S-shaped metal patterns to converge radiating beams outputted from the radiating element.

A data access system includes a plurality of access points and an antenna corresponding to one of the access points. The antenna includes a planar monopole, a vertical ground plane and a top horizontal ground plane. In one aspect, the top horizontal ground plane outwardly extends over the planar monopole for a distance that is generally between three-quarters to three-halves of the length of the planar monopole.

A planar dipole antenna comprises a dielectric substrate, two radiation conductors, and a transmission line. The two radiation conductors are formed on the dielectric substrate and separated by a predefined distance. Each radiation conductor includes first and second metal plates, and a meandered metal line. The meandered metal line has two ends and at least three bending points. One end of the meandered metal line is connected to the first metal plate, while the other end is connected to the second metal plate. This antenna increases the receiver's gain up to 6.8 dBi through the use of the current distribution of three equal-phase areas. This overcomes the drawback of a conventional antenna with receiver's gain only about 2.2 dBi. This planar dipole antenna has a simple structure of single-sided circuitry, and is easily formed on the dielectric substrate by a standard printing or etching process.

An apparatus of antenna with heat slug and its fabricating process are provided, in which the antenna with heat slug can be realized with a single sheet or double sheets of metal. Each single sheet of metal can be achieved by simply cutting and bending a metal plate. Thereby, it is a simple and low-cost fabricating process. In the known fabricating process of integrated circuit, the heat slug and the antenna can be combined in a module at the same step. Therefore, integrating the antenna with heat slug in a fabricating process needs not to develop a new process.

An integrated antenna for mobile communications. A short-circuiting metal cylinder is provided in the antenna for arranging other functional modules such that the antenna and related circuits may have better integration. The provided antenna includes a ground with a via-hole; a radiating member arranged on the ground and having a feeding portion for receiving signals via electrical connection through the via-hole; and a short-circuiting member having a space, a first end of which is electrically connected to the ground substantially vertically, and the other end of which is electrically connected to the radiating member. The radiating member further includes a first sub-radiating member, a second sub-radiating member and a third sub-radiating member. The first sub-radiating member is substantially triangular, and the second sub-radiating portion is substantially parallel to the ground. The third sub-radiating member is substantially parallel to the first sub-radiating member.

An apparatus of antenna with heat slug and its fabricating process are provided, in which the antenna with heat slug can be realized with a single sheet or double sheets of metal. A dual-band antenna module with a mask cover is taken as an example to realize the apparatus. Each single sheet of metal can be achieved by simply cutting and bending a metal plate. Thereby, it is a simple and low-cost fabricating process. In the known fabricating process of integrated circuit, the heat slug and the antenna can be combined in a module at the same step. Therefore, integrating the antenna with heat slug in a fabricating process needs not to develop a new process.

A wireless apparatus capable of controlling radiation patterns and directions of antenna is provided. It comprises an antenna element, a ground plane, an antenna feed-point, and at least one slot or slit formed on the ground plane. The inclusion of such slots or slits in the wireless apparatus improves the radiation directivity of antenna, and greatly enhances the antenna gain on the horizontal plane. It also resolves the problems caused by shift of radiation patterns of antenna and the poor antenna gains for a conventional antenna apparatus. The wireless apparatus of the present invention has the advantages of simple structure and easy fabrication. The invention can be applied to various kinds of antennas, such as monopole antenna, shorted-monopole antenna, dipole antenna, loop antenna, and planar inverted-F antenna, etc.
