Dual-Polarized Planar-Printed Ultrawideband Antenna Array on a Triangular Grid

IEEE Transactions on Antennas and Propagation, 2020
This article presents a dual-polarized planar-printed ultrawideband antenna array on an optimally sampled triangular (hexagonal) lattice. The design is based on the dual-polarized planar ultrawideband modular antenna (PUMA).

The number of triangular islands on a triangular grid

Periodica Mathematica Hungarica, 2009
Using lattice theory, \textit{G.~Czédli} [Eur. J. Comb. 30, No 1, 208--215 (2009; Zbl 1187.05024)] has obtained a sharp upper bound for the number of rectangular islands. His methods are applied in the paper under review to estimate the number \(f(n)\) of triangular islands on a triangular grid with the side length \(n\): \((n^2 + 3n)/5 \leq f(n) \leq (

Binary Tomography on Triangular Grid Involving Hexagonal Grid Approach

International Workshop on Computational Intelligence and Applications, 2018
In this paper, we consider the binary tomography reconstruction problem of images on the triangular grid. The reconstruction process is based on three natural directions of projections, defined by the lane directions of the triangular grid (they are analogous to row and column directions on the square grid).

Weighted Distances on a Triangular Grid

International Workshop on Computational Intelligence and Applications, 2014
In this paper we introduce weighted distances on a triangular grid. Three types of neighborhood relations are used on the grid, and therefore three weights are used to define a distance function. Some properties of the weighted distances, including metrical properties are discussed.
