The utility model belongs to the field of structural design of helicopters, and particularly relates to a helicopter conformal antenna with horizontal omnidirectional gain. The radiator is arranged bymeans of the appearances of the oblique beam front edge fairing and the oblique beam rear edge fairing, and the advantage that no obstacle exists around the oblique beam of the helicopter is fully utilized, so that the antenna is designed. The antenna not only gives play to the advantages of the conformal antenna integrating the functions of dimensional rectification and radio frequency signal transceiving, but also improves the horizontal omnidirectional average gain of the conformal antenna, and reduces the out-of-roundness of the gain in the horizontal direction. 本实用新型属于直升机结构设计领域，具体涉及一种水平全向增益的直升机共形天线。通过借助斜梁前缘整流罩、斜梁后缘整流罩的外形设置辐射体，充分利用直升机斜梁四周无障碍物的优势，设计了本实用新型的天线。该天线不仅发挥了共形天线集成维形整流与收发射频信号功能的优势，又提高了共形天线的水平全向平均增益，降低了水平方向上增益不圆度。
