Affine transformation for synthesis of low sidelobe patterns in planar array antennas with a triangular element grid using the IFT method
TL;DR: In this article, a combination of the IFT method with an affine transformation is used to synthesize low sidelobe tapers for array antennas featuring a triangular grid, where the peak sidelobe levels of the obtained tapers are invariant with frequency and scan angle.

S.A. Bokhari,Narayanaswamy Balakrishnan,P.R. Mahapatra +2 more
- 15 Jun 1987
TL;DR: A hexagonal DFT convenient for triangular grid phased array computations is described and an algorithm for fast computation has been developed that is remarkably simple to code and requires about the same number of operations as the vector radix algorithm.

Method for determining amplitudes and phases of the different channels in an electromagnetic signal transmission network, such as a telecommunication satellite antenna
Jacques Sombrin
- 04 Jun 1999
TL;DR: In this paper, a method for determining amplitudes and phases of the different channels in an electromagnetic signal transmission network whereof the sources are arranged in a triangular lattice is described. But this method is not suitable for the case where the source is located in a fixed position.

TL;DR: In this paper, the DFT-UTD-based technique is extended to deal with the efficient evaluation of the near and far-field radiated by hexagonal arrays made of free-standing dipoles in a triangular lattice.

The processing of hexagonally sampled two-dimensional signals
Russell M. Mersereau
- 01 Jun 1979
TL;DR: Methods for the processing of two- dimensional signals which have been sampled as two-dimensional hexagonal arrays are presented and some comparisons between the two methods for representing planar data will also be presented.
A triangular arrangement of planar-array elements that reduces the number needed
TL;DR: In this article, it was shown that by placing the elements of a beam-scanning planar antenna array in a triangular pattern rather than a rectangular pattern, the number of elements needed in the array is reduced.
