Distance measurement tasks in micromachine tools need to be performed with micrometer accuracy. For such tasks, frequency-modulated continuous-wave (FMCW) radars with a combination of frequency and phase evaluations are a good choice. However, the ac

Ultrawide Bandwidth 180°-Hybrid-Coupler in Planar Technology

Autor: Thomas Zwick, P. Pahl, Serdal Ayhan, Steffen Scherr, Grzegorz Adamiuk

Publikováno v: International Journal of Microwave Science and Technology. 2014:1-6

A new concept of an ultrawide bandwidth 180°-hybrid-coupler is presented. The ultrawideband design approach is based on the excitation of a coplanar waveguide (CPW) mode and a coupled slot line (CSL) mode in the same double slotted planar waveguide.
