A Novel Approximate Antenna Pattern for Directional Antenna Arrays

摘要

The antenna pattern model plays a key role in evaluating the performance benefits of directional antenna arrays. In this letter, we propose a novel antenna pattern, named multi-cosine antenna pattern, to approximate the actual antenna pattern, and apply it to millimeter wave (mm-wave) networks. To get deep insights on the role of directional antenna arrays in mm-wave networks, we derive exact expressions for the success probability of the typical receiver as well as a tight upper bound. The results show that the proposed antenna pattern provides a better tradeoff between the accuracy and the tractability in terms of both antenna pattern and analysis than previous models.
