We report on the dependence of curvilinear-shaped coplanar waveguides on the near-field diffraction (NFD) patterns of spin waves propagating in perpendicularly magnetized thin films. Implementing the propagating spin-wave spectroscopy techniques on either concentrically or eccentrically shaped antennas, we show how the link budget is directly affected by the spin-wave interference, in good agreement with NFD simulations. This work demonstrates the feasibility of inductively probing a magnon interference pattern with a resolution down to 1μm2, and provides a methodology for shaping spin-wave beams from an antenna design. This methodology is successfully implemented in the case study of a spin-wave Young's interference experiment.
