A wideband bow-tie antenna using suspended stripline balun

In this paper, the design of a wideband bow-tie antenna using suspended stripline (SSL) balun is presented. The utilized balun is composed of a wideband multi-section power divider and a left-handed nonlinear transmission line (LH NLTL) implemented with SSL. The fabricated balun exhibits wide frequency bandwidth form 4 to 18GHz (127%). To demonstrate applicability of the proposed balun, a modified bow-tie antenna is built and tested. The fabricated antenna provides wide frequency bandwidth from 5 to 18GHz (110%) and the measured gain of typical 3.5 dBi with quasiomni directional radiation patterns.
