Wideband split-ring antenna arrays based on substrate integrated waveguide for Ka-band applications

Abstract: This paper presents wideband split-ring antenna arrays based on substrate integrated waveguide (SIW) for Ka-band (26.5–40 GHz) applications. The antenna array is fed by a 2.92 mm coaxial connector (K-connector) and the power is equally distributed to each split-ring resonator. The designed coplanar waveguide (CPW), SIW, CPW-to-SIW transition, coaxial-to-CPW transition, and two-stage SIW power divider are described in detail. By using a thin Rogers 6002 substrate with silver epoxy-filled vias, a transition prot… Show more

“…Smooth propagation modes conversion from coaxial to CPW and CPW to SIW is necessary to obtain wideband performance. The E field distribution (Figure 6 in [96]) in the designed back-to-back transition prototype has shown that the coaxial mode has been generated at the input terminal (at the connector), CPW mode generated at the end of the coaxial to CPW transition, and finally, the SIW mode generated at the end of the CPW to SIW transition. Hence, the designed transition has exhibited a wider impedance bandwidth (26 GHz to 40 GHz).…”
