  • Patent number: 10516467
    Abstract: According to an example embodiment, there is provided an apparatus comprising circuitry configured to derive at least two outputs, wherein each output comprises a sum of at least two intermediate signals, the circuitry being configured to derive each intermediate signal by applying a coefficient to a signal received from an antenna element, each output corresponding to an antenna beam, and at least one processing core configured to select from a preconfigured plurality of coefficient sets a first set of coefficients, and to provide the selected first set of coefficients to the circuitry for use in deriving the intermediate signals, the selection being based at least in part on an operating condition relating to the apparatus. The coefficients may be chosen to decrease a correlation between the antenna elements, for example.

  • Patent number: 7864117
    Abstract: 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.
