An investigation of hybrid hexagonal and conical antenna arrays

In this paper, various types of hexagonal and conical antenna arrays constructed based on elliptical shape are presented. These types are called HA, CHA, HCA, HCCA, ECOA, ECCOA, HCOA and HCCOA where only the array factors are considered. The effect of the element factor can be considered separately and combined to the array factor. The expressions for all array factors have been obtained. HA is treated as consisting of two concentric N-element elliptical arrays of different semi-major and semi-minor axes and ECOA is treated as EApsilas that are placed one above another, so that the semi-major and semi-minor axes of each EA decrease linearly.
