Abstract

Electromagnetic band-gap (EBG) structures exhibit unique electromagnetic properties that have led to a wide range of applications to the antenna and propagation fields. This paper investigates the performance of a waveguide end-slot phased array (WESPA) antenna integrated with mushroom-like EBG structures. The mushroom-like EBG structure has the advantage of compactness and offers the capability to block the surface wave coupling of the phased array, which provides a possible solution to the "blind spots" problem of the WESPA. Some novel and efficient EBG array configurations are proposed, and an infinite phased array and a finite phased array of 3 × 9 slot elements are analyzed. The tradeoffs and design considerations of EBG structures are discussed to obtain optimum performance.
