    Abstract: An antenna operable over a predetermined range of frequency includes a transmission line, a transformer network connected to one end of the transmission line, and at least one ferrite/powder iron network connected to an opposite end of the transformer network. The ferrite/powder iron network changes the effective electrical length of the antenna such that as the frequency of operation changes, the current distribution above and below the network changes in corresponding manner. A second ferrite/powder iron network may be serially positioned with respect to the other network, wherein both function to reduce the current thereabove. Accordingly, as the frequency of operation increases, the electrical height of the antenna decreases. The network also encompasses a way to safely dissipate otherwise destructive heat created by the operation of the antenna system at high radio-frequency power.

The buoyant cable antenna is designed with an antenna wire that is divided into N equal length segments of length d/2. A capacitor is coupled between every other segment such that capacitors are separated by a distance d. A shunt inductor is coupled to the antenna wire between the adjoining segments not separated by a capacitor such that the shunt inductors are separated by a distance d. This antenna design provides a substantially improved impedance bandwidth over existing prior art antennas at high frequency without increasing the physical profile of the antenna and without the use of active circuit elements.

    Abstract: A multi-band antenna device includes a primary antenna with a helical component and a folded component. A wire is formed in a helix to construct the helical component and a wire is formed in a folded-over fashion to form the folded component. The folded component is disposed inside the helix. The helical component and folded component may be formed with separate wires or as one continuous wire. The primary antenna is for resonating in multiple frequency bands including a first frequency band correlated with the helical component and a second frequency band correlated with the folded component. A secondary antenna may be included to provide diversity and possibly other frequency bands. The secondary antenna includes a planar inverted F antenna.

  • Patent number: 7750858
    Abstract: A drawer structure of a rod-shaped body, which does not require a complicated inner structure, is provided. In a present preferred embodiment, a structure draws a rod-shaped body out of a housing for housing the rod-shaped body. A guide for holding the rod-shaped body so that the rod-shaped body can be rotated about an axis and slid in the direction of the axis, and an encasing surface which crosses at a predetermined angle to the axis of the rod-shaped body are formed on the housing side. The rod-shaped body has an internal surface facing to the encasing surface, and a cap is formed at a tip of the rod-shaped body so that the internal surface may be a predetermined angle to the axis of the rod-shaped body. When the rod-shaped body is inserted into the guide and the rod-shaped body is rotated from a state where the encasing surface and the internal surface are contacted with each other, the rod-shaped body performs a translatory movement in an axial direction of the guide according to the cam effect.

  • Publication number: 20100090908
    Abstract: The present invention relates to a parallel-ring type antenna which is reduced in entire physical length, and has a wider bandwidth and a more excellent return loss, while having the same resonant point, by changing a loading portion of a retractable antenna employing a top-loading method that can easily secure the physical length of the antenna. Further, characteristics electrically similar to those of a helical antenna can be achieved by applying the parallel-ring type to the loading portion of the monopole termination. In addition, the entire length of an antenna can be reduced, while accomplishing the same resonance as that of the helical antenna, by employing a change in return loss according to a change in the thickness of the parallel ring, the distance between the rings, the diameter of the ring, and/or the length of the loading portion.
