Patent number: 8456375Abstract: In a dielectrically-loaded multifilar helical antenna, a conductive phasing ring is arranged between and couples together feed nodes and the helical radiating elements. The phasing ring includes an annular conductive path having an electrical length equivalent to a full wavelength at the operating frequency so as to be resonant at that frequency. The helical elements are coupled to the outer periphery of the phasing ring at respective spaced apart coupling locations. The helical elements may include open-circuit or closed-circuit elongate conductive tracks, or a combination of both. In the case of the helical elements being closed-circuit tracks, these tracks are interconnected by a second resonant ring, which is resonant at the same frequency as or a different frequency from the first resonant ring. The invention is applicable to both end-fire and back-fire helical antennas.Type: GrantFiled: July 2, 2010Date of Patent: June 4, 2013Assignee: Sarantel LimitedInventor: Oliver Paul Leisten

Patent number: 8427388Abstract: Symmetrical eight-shaped balun (BALanced-to-UNbalanced converter) comprising a first and second eye, each eye comprising conducting tracks forming turns. The eyes comprise an equal number of primary turns that form a first conducting path from a first terminal to a second terminal, in which in operation electrical current flows in a first direction in a first eye and in a second direction in a second eye. Moreover, the eyes further comprise an equal number of secondary turns that form a second conducting path from a third terminal to a fourth terminal, in which in operation electrical current flows in a first direction in a first eye and in a second direction in a second eye. The geometrical and electrical middle points of primary and secondary turns are all superposed and further are located in the same plane.Type: GrantFiled: November 23, 2010Date of Patent: April 23, 2013Assignee: ST-Ericsson SAInventors: Bassem Fahs, Lionel Guiraud, Hendrik Visser
