Broadband millimeter-wave quasi-Yagi antenna using substrate integrated waveguide technique

This paper presents a novel approach of designing broadband quasi-Yagi dipole antenna using Substrate Integrated Waveguide (SIW) techniques. The antenna configuration involves a newly proposed broadband microstrip-to-broadside parallel stripline transition and a two element printed quasi-Yagi array. As an antenna feeding network, the proposed transition is constructed on the basis of the SIW scheme which can achieve a broadband performance and offer several advantages over other counterparts such as low insertion loss, good design tolerance and compact circuit size over millimeter wave range. The design concept has been validated experimentally.
