Circularly polarized stacked-Yagi antenna with logarithmic spiral elements for E-band applications

Abstract

This paper presents a new stacked-Yagi antenna operating in the E-band that uses logarithmic spiral elements to achieve an ultra wideband response and circular polarization. An SIW structure is used to excite the spiral structure as the single element and a matching post is used as a balun. This element is then used in a vertical stacked-Yagi configuration… (More)
