  • Publication number: 20110050537
    Abstract: An antenna formed inside a film comprises a thin film, a radiation conductor, a supporter, a conductive paste and at least one contact terminal. The radiation conductor is arranged on the thin film. The supporter is arranged on the radiation conductor with at least one trench formed thereon. The contact terminal has a recession with a hole. The recession is inserted into the trench. The conductive paste is injected into the trench via the hole to have such a thickness that the top of the conductive paste exactly contacts the bottom of the recession. The present invention is characterized in that a conductive paste is used as a conduction medium and a buffer between the contact terminal and the radiation conductor. Thereby, the present invention can overcome the conventional problem that the radiation conductor and thin film are likely to be damaged in the fabrication process.

  • Patent number: 7683840
    Abstract: An integrated broadband antenna device with wide band function is disclosed. The antenna device comprises a ground plate, a feeding wire, a first metal radiator, a second metal radiator, a ground metal radiator and a parasitic metal radiator. The first metal radiator is connected with the positive ends of signals of the feeding wire for transmitting electric signals and producing a high frequency mode. The first metal radiator is coupled to and energizes the second metal radiator and the parasitic metal radiator, and then the two metal radiator producing a low frequency mode and a second high frequency mode along with the ground metal radiator obtains a wider bandwidth. The broadband antenna device integrating various kinds of antennas is able to have a enough bandwidth to meet the requirements of AMPS (824˜894 MHz), GSM (880˜960 MHz), GPS (1575 MHz), DCS (1710˜1880 MHz), PCS (1850˜1990 MHz), UMTS (1920˜2170 MHz) and Wi-Fi (2400˜2500 MHz).

  • Patent number: 7352329
    Abstract: A multi-band antenna with the broadband function is based upon a planar inverted-F antenna with two conductive arms and a ground. The two conductive arms extend from the ground near the two opposite ends of the ground. Two radiation plates of the two conductive arms extend toward each other. The multi-band antenna has a sufficient large band at high frequencies. Since the conductive arms are disposed close to the two ends of the ground, operations of bending the two conductive arms or soldering a feed wires are simpler and have a higher yield.

  • Publication number: 20060139228
    Abstract: Provided is an ultra-wideband dipole antenna. In one embodiment, the antenna comprises a first outer sleeve, an intermediate sleeve surrounded by the first outer sleeve, a second outer sleeve above the first outer sleeve, a conductive interconnection interconnected the outer sleeves, and an inner coaxial conductor surrounded by the intermediate sleeve. A distance between the first outer sleeve and the intermediate sleeve can be changed for adjusting the generated capacitance for obtaining a required impedance matching in the resonance mode of an antenna operating bandwidth and an ultra-wideband characteristic. The antenna is particularly suitable for operating in a frequency range of 2.1 GHz to 11.7 GHz.
