H-plane SIW active horn antenna

This paper presents a H-plane active horn antenna based on SIW technology. The amplifiers are fully integrated within the SIW structure by replacing the top layer by a frequency selective surface operating in stop-band. Results show 3 to 5 dB gain improvement in the H-plane and E-plane measurements.This work was supported by the Gobierno del Principado de Asturias under the Plan de Ciencia Tecnología e Innovación (PCTI) by Grants BP13042 and BP12032, by the Gobierno del Principado de Asturias and FEDER (Uni´on Europea) under Project GRUPIN14-114, and by the Ministerio de Economía y Competitividad under Project TEC2014-54005-P
