A bent-ends spiral antenna above a fan-shaped electromagnetic band-gap structure

This paper describes radiation characteristics of a bent-ends two-arm Archimedean spiral antenna above a fan-shaped electromagnetic band-gap (EBG) structure. The EBG structure consists of fan-shaped EBG patch cells. The fan-shaped EBG patches are arranged homogeneously in the circumferential direction but are set non-homogeneously in the radial direction… CONTINUE READING
