Patent number: 7274340Abstract: An antenna module has a substrate, first and second coupling elements, and first and second resonant circuits disposed on the substrate. The first and second coupling elements are mounted to the substrate and particularly adapted to couple respective first and second frequency bands to a ground plane through respective first and second ports. The first resonant circuit has a plurality of components having electrical values selected so as to function as a band-pass filter within the first frequency band and to present a high impedance at least in the second frequency band. The second resonant circuit is coupled to the second port and has a plurality of components that have electrical values selected so as to function as a band-pass filter within the second frequency band and to present a high impedance at least in the first frequency band.Type: GrantFiled: December 28, 2005Date of Patent: September 25, 2007Assignee: Nokia CorporationInventors: Sinasi Ozden, Bjarne K. Nielsen, Claus H. Jorgensen, Juha Villanen, Clemens Icheln, Pertti Vainikainen

Patent number: 6903692Abstract: The invention relates to a dielectric antenna, particularly suited to portable radio devices. The feed conductor (231) of the antenna is shaped so that it at the same time in itself serves as a radiator in the same frequency range as the dielectric resonator (220) of the antenna. The resonance frequencies of the feed conductor and the dielectric resonator are advantageously arranged to be so near to each other that there is formed a united operation band. The feed conductor is advantageously located on a surface (223) of the dielectric element. The structure may also include parasitic conductors. For the antenna according to the invention, there is obtained a larger bandwidth than for corresponding antennas of the prior art. Moreover, the air gaps between the feed conductor and the dielectric element are avoided, as well as resulting changes in the electric properties.Type: GrantFiled: May 28, 2002Date of Patent: June 7, 2005Assignee: Filtronic LK OyInventors: Outi Kivekäs, Jani Ollikainen, Jaakko Juntunen, Pertti Vainikainen

Patent number: 6650295Abstract: A radio antenna comprising a tuning component, such as a transmission line, coupled to the radiating element for providing a frequency shift from the resonant frequency, and an adjustment mechanism for adjusting the frequency shift by effectively changing the length of the transmission line. The adjustment mechanism comprises one or more extension lines, and a switching mechanism, which can be closed to couple one or more of the extension lines to the transmission line. The tuning component can also be one or more lumped reactive elements.Type: GrantFiled: January 28, 2002Date of Patent: November 18, 2003Assignee: Nokia CorporationInventors: Jani Ollikainen, Outi Kivekäs, Pertti Vainikainen

Patent number: 6008764Abstract: The invention relates to antenna structures, particularly to substantially planar broadband antennas realized by microstrips. The antenna structure according to the invention has at least two superimposed strips (10, 20), which have a length of about a quarter-wave and which at one end are short circuited to the ground plane (30). The strips (10, 20) have certain resonance frequencies, which are tuned close to each other so that the operating band of the antenna structure is substantially continuous.Type: GrantFiled: March 24, 1998Date of Patent: December 28, 1999Assignee: Nokia Mobile Phones LimitedInventors: Jani Ollikainen, Pertti Vainikainen
