Device-to-Device (D2D) communications are considered as a keystone of the fifth generation wirelesstechnology (5G). This new approach is very promising in terms of energy and spectrum efficiency.However, the integration of such communications in a typical cellular network increases inevitably theamount of interference. Several researches propose to lower the interference thanks to either sharingthe cellular spectrum intelligently, or using non-cellular bands for D2D links. In this paper, we focuson the latter opportunity, and consider that the D2D communications are used with millimeter waves(mmWaves).For what comes to modeling a D2D-enabled (D2D-e) network, many works propose to use stochasticgeometry so as to evaluate the impact of interference and noise on the various links. In this work, weaim to analyze the SINR and the average data rate of Outband D2D links for user equipments (UEs) withconventional omnidirectional antennas and with various directional mmWave antennas: patch antennas,horn antennas and uniform linear array antennas. Analytical and empirical evaluations of the Signal-to-Interference-plus Noise Ratio (SINR) are made with stochastic geometry. We propose to discuss theadvantages and drawbacks of directional mmWave antennas in Outband D2D for various antennadesigns, and their interest in various environments.
