PROBLEM TO BE SOLVED: To obtain a microstrip antenna assembly in which a plurality of microstrip antennas is installed in parallel, which improve performance and practicality more, while the each microstrip antenna can achieve a function as a broad band antenna. SOLUTION: The microstrip antenna 10 is provided with: a box type conductor plate 11 formed in a box shape with a bottom; a radiation conductor plate 13 which is prepared in nearly parallel to a bottom face 11a taking a predetermined space d from the bottom face 11a of the box type conductor plate 11; a pair of feeding conductor plates 14a which is electrically connected to two sides which face each other in the radiation conductor plate 13, and installed extending toward the bottom face 11a of the box type conductor plate 11; and feeding pins 15 which are electrically connected to a pair of the feeding conductor plates 14a, and can perform feeding of different phase of 180°.
