Topic The partial reflection surface antenna which can improve the performance by applying the partial reflection surface antenna to antenna module, is offered.SolutionsThe substrate 11 which has upper surface 221 mainly, furthermore the signal to establish the input port Out on upper surface, 221 to receive and output the high frequency signal, reflector 22 to use for the reflection of the said high frequency signal of part, first antenna array and to lay second antenna array on the surface of reflector 22, furthermore the said second antenna array to encircle the said first antenna array, multiple support units to support reflector 22 with upper surface 221 of substrate 11, furthermore reflector to maintain the distance of specification between 22 and substrate 11, as for the said first antenna array multipleIt is constituted by one micro trip reflected unit 231, the said second antenna array is formed by multiple second micro trip reflected units 232, the interval distance which is located between first micro trip reflected unit 231 is smaller than interval distance between second micro trip reflected unit 232.
