| Summary: | The complexity of the actual antenna pattern imposes restrictions on investigating the benefits of directional antenna arrays in large-scale networks.Hence,a novel multi-level flat-top antenna pattern was proposed to approximate and simplify the actual one and was applied in millimeter-wave cellular networks for performance analysis.To fully characterize the impact of the directional antenna array on the user performance,stochastic geometry was adopted to establish an analytical framework for millimeter-wave cellular networks and derive the coverage probability and transmission rate of the typical user with the proposed multi-level flat-top antenna pattern,including the exact and bounding expressions.The simulation results show that the proposed antenna pattern provides a better tradeoff between the accuracy and tractability than previous patterns. |
