Abstract :
In this work a new integrated scheme of frequency selective transmission based on electromagnetic band gap (EBG) technology is presented. In the proposed configuration the radiofrequency signal is received by an EBG horn antenna and then filtered by an EBG cavity via the resonant coupling between two closed EBG waveguides and an EBG hollow defect (waveguide-to-cavity-to-waveguide coupling). The paper presents the designs of novel EBG horn antennas with competitive characteristics and demonstrates the concept of using different types of hollow EBG defects, such as point defects, void-like defects and tapers, for creating compact, efficient and integrated devices for submillimetre wavelenghts.
