A perfect anomalous reflector is designed by employing the receiving and scattering array antenna theory to optimize characteristics of a planar reflecting surface. For periodic reflectors with supercell consisting relatively few reactively loaded radiating elements, reflection amplitudes into propagating Floquet modes are controlled in an algebraic optimization load reactances, avoiding brute-...

This paper proposes the development and design of double layer metamaterials based on electromagnetic band gap (EBG) rods as a superstrate of a resonator antenna to enhance required antenna characteristics for the mobile base station. The metallic rod type metamaterial can partially reflect wave of a primary radiator. The antenna was designed and analyzed by a simulation result from CST Microwa...

Satellite broadcasting of UHDTV in Japan has used the 12-GHz band (11.7 to 12.75GHz) since 2018. The 21-GHz (21.4 22.0GHz) also been allocated satellite Europe, Africa, and Asia Pacific. BSAT-4a not only 12-GHz-band transponders for services, but 21-GHz-band experimental future services. To receive services using these two frequency bands with a single antenna, we designed 12- dual-band horn an...
