Using a multielement antenna, we have performed measurements of the angular dependence of propagating magnetostatic spin waves in a thin yttrium iron garnet film, both in-plane and out-of-plane, and compared the measurements with existing theoretical models. For most magnetic field directions, we report theory and experiments agree reasonably well. However, there is a range of magnetic field directions where differences between theory and experiment become large.
