  This paper aims to provide a robust model for the well-known phenomenon of
K\'arm\'an Vortex Street arising in Fluid Mechanics. The first theoretical
attempt to model this pattern was given by von K\'arm\'an [22, 23]. He
considered two parallel staggered rows of point vortices, with opposite
strength, that translate at the same speed. Following the ideas of Saffman and
Schatzman [36], we propose to study this phenomenon in the Euler equations by
considering two infinite arrows of vortex patches. The key idea is to
desingularize the point vortex model proposed by von K\'arm\'an. Our
construction is flexible and can be extended to more general incompressible
models.
