Patent number: 7864117Abstract: A microstrip patch antenna wherein the half-power beamwidths of two orthogonal polarizations can be widened or narrowed in desired frequency bands around its center frequency. The result is a wideband or multiband antenna with desired beamwidth characteristics. In particular, the antenna can be arranged to be singly-polarized, dual-polarized or circularly-polarized. Using at least two parasitic patches on each of the two opposing sides of a primary radiating patch, both E-plane (electric field) and H-plane (magnetic field) parasitic couplings can be simultaneously achieved. By introducing uneven current distribution along the patch principal axis, some sub-bands of the antenna pattern can be beam steered.Type: GrantFiled: May 7, 2008Date of Patent: January 4, 2011Assignee: Nokia Siemens Networks OyInventors: Jouko Aurinsalo, Jussi Säily

Patent number: 7471247Abstract: An antenna array includes a plurality of antenna unit cells, a ground plane, and at least one artificial magnetic layer AML unit cell. At least one AML unit cell is disposed between at least two adjacent ones of the antenna unit cells. The AML unit cells include a pair of split ring resonators through a ring dielectric layer, and the resonators are capacitively coupled to the a ground plane of the antenna array through a capacitor dielectric layer. The resonators are orthogonal to one another and to the ground plane, and more than one pair may be defined in each AML unit cell. Magnetic energy from the antenna unit cells induces an electric field in the resonators, and the resulting magnetic field is strongly coupled to the AML unit cell to inhibit mutual coupling between radiating elements by suppression of surface wave propagation.Type: GrantFiled: June 13, 2006Date of Patent: December 30, 2008Assignee: Nokia Siemens Networks, OyInventors: Jussi Säily, Mikko Kaunisto, Sergei Tretyakov, Constantin Simovski

Patent number: 7423595Abstract: A dual-polarized microstrip patch antenna structure comprising: a dual microstrip feed line circuitry underneath a bottom dielectric substrate; a ground plane layer overlying the bottom dielectric substrate, the ground plane layer having coupling apertures etched to the ground plane layer; a middle metallized patch layer stacked over a middle dielectric substrate; a top metallized patch layer stacked underneath a top dielectric substrate; and an air layer between the middle dielectric substrate and the top dielectric substrate separating the middle metallized patch layer and the top metallized patch layer. The microstrip feed line circuitry is configured to utilize corner-feeding techniques for enabling diagonal modes of the patch layers, and the coupling apertures of the ground plane layer are provided with a non-resonant bow-tie shape for enabling aperture coupling between the microstrip feed line circuitry and the patch layers.Type: GrantFiled: November 16, 2006Date of Patent: September 9, 2008Assignee: Nokia CorporationInventor: Jussi Säily
