A millimeter-band dielectric embedded dual-beam antenna is designed and simulated, which is based on microstrip antenna theory, the Yagi antenna principle and the design method of dielectric embedded microstrip antenna. The antenna buries improved planar printed microstrip Yagi antenna in the dielectric to form a dielectric embedded antenna. The director element of traditional Yagi antenna is changed from one to two, which is used to constrain the beam direction and increase the gain. By using an additional parasitic patch to improve the antenna, a larger relative impedance bandwidth is obtained, and the relative bandwidth is increased from 6.87% to 7.62%, and the gain is 9.96dB, which can be applied to short-distance communication and has good application value.
