An upper bound on the effective area and bandwidth product for linearly polarized array antennas is derived. The bound is based on the forward scattering sum rule that relates the antenna properties with the polarizability of the antenna structure. The results are illustrated for a dipole array and a capacitively loaded dipole array with numerical simulations.
