The model star-branched macromolecules were constructed of identical segments which positions were restricted to vertices of a simple cubic lattice. The chains were modeled at good solvent conditions and the excluded volume was the only interaction between the polymer segments. The model chain interacted via a simple contact potential with an impenetrable planar surface consisting of two kinds of points: attractive and repulsive arranged into strips. The properties of the system were determined by means of Monte Carlo simulations. The structure of adsorbed chains was found to be strongly dependent on the distance between the repulsive stripes when this distance was short and compared to the chain's size.
