Generalised design method of broadband array antennas using curved geometry

Abstract: Curved array antennas offer increased degrees of freedom when antenna elements are configured in non‐uniform geometries. This permits increased flexibility over control of pattern structure and increase in the bandwidth of operation. In this study, the authors present a generalised design method for broadband antenna arrays using such curved structures. Following this design process, two types of array structures evolved: pseudo‐curved array (PCA), with the array apertures parallel to one another and the fully… Show more

“…It is reported in [24] that the maximum scan angle can be increased from 50 • to more than 90 • by placing a linear array on a cylindrical surface and the scan range for the bent antenna array can be significantly improved by an appropriate choice of the array bending angle. In [25], a narrowing of multibeam positions and a broader frequency range were observed in the rectangular waveguides array on the curved geometry as compared to a planar array. Reflection coefficient and radiation patterns of different antennas due to bending were investigated in [26]- [30].…”

“…In broad, the split ring resonator acquires unusual property such as negative permeability and negative permittivity. 10,11 To validate the occurrence of negative permeability characteristics in the proposed CSRR structure, waveguide method is used to describe. The proposed circular split ring structure is placed within waveguide on the FR-4 as revealed in Figure 6A.…”
