Abstract :
In this letter, we present a novel approach to design a novel dual-band sectoral antenna by combining metallic electromagnetic band-gap (EBG) materials as a superstrate with a frequency-selective surface (FSS) as a substrate, thus making it possible to circumvent the narrow bandwidth problem. This antenna operates according to a sectoral radiation pattern form presenting a half-power beamwidth of at least 60deg. Using the multisource technique, we carry out a network of interlaced radiant apertures that makes it possible to obtain a more important directivity by summation of the apertures´ contribution. The geometry and characteristics of the antenna are detailed, and a design method is proposed.
