A method and apparatus in one example uses adaptive digital beamforming with a plurality of heterogeneous antennas which are more affordable and flexible and do not require the use of a nuller antenna. The method uses adaptive, multi-beam digital beamforming without knowledge of a signal direction or aperture of the antena. The method works with arbitrary antenna elements in arbitrary locations and does not require any a priori antenna model. The method also optimizes signal-to-noise ratio (SNR) of the received signal.

An apparatus substantially updates all the phase shifter values of a phased array antenna by using “global write” to update these parameters to all phased-array transformation circuits simultaneously via a serial bus. Antenna elements, each controlled by a phased-array transformation circuit, are individually configured to transform phase and gain according to a register array. The register array has a local register group and a central register group, the local registers physically placed close in proximity to RF chains which each correspond to an element of array antenna, whereby each set of local registers control an individual antenna element and a central register controlling overall beam steering function. The apparatus is configured to efficiently elaborate phase shift weights into a submodule of a phase array antenna system with low noise and bandwidth.

The present invention relates to an antenna comprising multiple array elements with a first and second feeding point, each associated with orthogonal polarizations, each array element has a first and second phase centre each associated with the orthogonal polarizations, the first and second phase centres of said array elements are arranged in at least two columns, and one antenna port connected to the first and second feeding points of at least two array elements with first phase centre and second phase centre arranged in the at least two columns via a respective feeding network. The feeding network comprises a beam forming network having a primary connection, connected to the antenna port, and at least four secondary connections. The beam forming network divides power between the first feeding point and the second feeding point and controls phase shift differences between the respective feeding points with phase centre arranged in different columns.

A lightweight deployable antenna assembly for, e.g., microsatellites including multifilar (e.g., quadrifilar) antenna (MHA) structures rigidly maintained in an array pattern by a lightweight linkage and collectively controlled by a central antenna feed circuit and local antenna feed circuits to perform phased array antenna operations. The linkage is preferably an expandable (e.g., flexural-scissor-grid) linkage capable of collapsing into a retracted/stowage state in which the MHA elements are maintained in a closely-spaced (e.g., hexagonal lattice close-packed) configuration optimized for payload storage. To deploy the antenna for operation, the linkage unfolds (expands) such that the MHA elements are moved away from each other and into an evenly spaced (e.g., wide-spaced hexagonal) pattern optimized for phased array operations. The MHA structures utilize modified helical filar elements including metal plated/printed on polymer/plastic beams/ribbons, or thin-walled metal tubes. The helical filar elements are radially offset (e.g., by 90°) and wound around a central axis.
