In response to the problem that ground ammunition fuze antennas cannot meet the requirements of wide angle detection,this paper proposed a wide beam generation method based on conformal array antenna technology.By using dipole and microstrip antenna arrays conformally on the inner surface of the fuze hood,the lateral omnidirectional radiation characteristics were achieved.The antenna designed by this method could change with the shape of the wind cap without occupying extra space.The test verification showed that the an-tenna had omnidirectional radiation characteristics and high gain on the H-plane.
