This In this paper we briefly describe QUBIC, the Q & U Bolometric Interferometer for Cosmology, a novel ground-based instrument designed to measure the extremely faint polarization anisotropy of the cosmic microwave background at intermediate angular scales. In particular we will describe simulations of the optical combiner and feedhorn array used to generate synthesized beam patterns for each detector on our focal plane. A QUBIC technical demonstrator has been built and is being installed in the observing site at Alto Chorrillos, Argentina with first light expected in 2022.
