摘要

The antenna pattern model is critical to analyze the cellular coverage in mobile communication system, especially for the millimeter-wave (mmW) communication system. In this paper, we propose an accurate yet tractable antenna model for the Uniform Linear Array (ULA), which approximates all lobes by multiple scaled and shifted cosine functions, each with the constant beam gain. Based on this antenna model, we derived exact expressions for the coverage probability by employing the Poisson Point Process (PPP) distribution of base stations. It has been shown that our analytical model can match well as long as the compensation factor is properly selected.
