DESIGN OF A SIMPLE HOLOGRAPHIC ANTENNA LAYER IN THE KA BAND (30 GHZ)

Abstract

The study of holographic antennas dates from the 60s; although they were initially relegated to the background, interest in them has been increasing since the development of new wireless communication systems thanks to their ease of integration and low costs. The present article aims at the design and simulation of a single-layer holographic antenna in the Ka band at 30GHz with a normal radiation pattern to the holographic surface to be used in LMDS applications. For this, a study of the state of the art of this technology was carried out, a design with a horn antenna as feeding antenna was proposed and the substrate plate feeder system in the HFSS software was simulated.From the obtained results, the conclusion is obtained of obtaining a pattern directed in a normal way to the holographic surface, a small design of easy integration and construction.
