  • Patent number: 7586463
    Abstract: The present invention discloses a portable personal communication device with an extendable helical antenna. This helical antenna is made of an elastic conductive spring, configured to change its height over a ground plane and along the antenna axis, mainly having two positions: a stowed position where the antenna is pressed down between the ground plane and a rigid cover, achieving a low profile; and an operational position where the rigid cover is removed and the antenna is extended by its own spring force, to a higher height, improving antenna gain. Normally, a second planar antenna may be placed over the same ground plane, not exceeding the footprint of the helical antenna, thus utilizing a compactly small volume and yet achieving a considerable electromagnetic decoupling between the antennas, due to their different radiation patterns.

  • Patent number: 7579994
    Abstract: An antenna includes a central loop and four adjacent coplanar eccentric loops. The central loop creates a magnetic field that is essentially perpendicular to the antenna. The centres of gravity of the four eccentric loops are essentially located on the periphery of the central loop and the eccentric loops are supplied in such a way as to predominantly create a rotating field in a plane parallel to the plane of the antenna. The eccentric loops can be associated in pairs of non-adjacent loops in such a way as to generate electromagnetic fields of opposite phases in the respective pair. In this way, the two loops of a pair can be connected such that the same current flows through them in opposite trigonometric directions. A radiofrequency generator can supply first and second excitation signals alternately on two outputs, respectively to the central loop and to the eccentric loops.
