Abstract

In this article the design and the construction of an ultrawideband (UWB) 3 dB hybrid coupler are presented. The coupler is realized in broadside stripline technology to cover the operating bandwidth 0.5 - 18 GHz (more than five octaves). Detailed electromagnetic design has been carried to optimize performances according to bandwidth. The comparison between simulations and measurements validated the design approach. The first prototype guaranteed an insertion loss lower than 5 dB and a phase shift equal to 90° +/- 5° in bandwidth
