- W4292348728 abstract "This paper presents a design of a right hand circularly polarized K-band reflectarray antenna at 18 GHz with a linearly polarized feed for downlink satellite communication (SATCOM) systems. A dipole antenna is used as linearly polarized (LP) feeding element for the proposed reflectarray. This dipole antenna is tilted w.r.t the x-axis by an angle 45° to introduce nearly equal polarizations in x and y directions on the aperture of the reflectarray. On the other hand, the reflecting element of the reflectarray have elliptical shapes. This elliptical shape is adjusted to produce a phase shift 90° between the reflection coefficients in x and y directions at each reflecting element. This phase difference converts the incident plane wave into circularly polarized reflected wave. Moreover, a new efficient technique is discussed in this paper for fast modelling the designed reflectarray. This technique is based on developing a Visual Basic Script file for allocating the reflecting elements with their corresponding dimensions in their location on the simulation tool. This script file is used directly by the simulation tool (HFSS) to draw the complete model automatically. This procedure has a significant role on simplifying the modeling of complicated structure like the proposed reflectarray." @default.
