Abstract:Novel broadband circularly polarized (CP) electromagnetic band-gap (EBG) antenna array was proposed in this paper. The antenna's radiating element is utilized by a microstrip-fed circular patch, radial slot, and three rectangular notches. The proposed antenna elements are fed by feeding network comprised form four hybrid couplers and microstrip lines with appropriate lengths to support desired phase difference at output ports. Radiating patches are sequentially rotated to enhance CP property and form a 4 × 4 a… Show more
