Bidirectional uniform irradiation antenna feed system

The invention relates to a bidirectional uniform irradiation antenna feed system. The system comprises a power division feed network (201) and multiple waveguide slit antenna arrays (118), wherein themultiple waveguide slit antenna arrays (118) are uniformly divided into two sets which are arranged up and down, each multiple waveguide slit antenna array (118) comprises eight waveguide slit antennas (402), the waveguide slit antennas (402) are arranged on a first power distributor (505) of the power division feed network (201), and the waveguide slit antennas (402) of the two waveguide slit antenna arrays (118) symmetric to each other up and down are arranged in a staggered mode. The system is advantaged in that bidirectional irradiation is employed, the top portion and the bottom portionrespectively have 32 waveguide slit antennas (402) which radiate to the middle, the radiation field is uniformly distributed, irradiation blind areas are effectively reduced, moreover, the waveguide slit antennas employ a stan
