PROBLEM TO BE SOLVED: To enlarge a directive control range of a microstrip array antenna. SOLUTION: In order to solve a matter that flexibility for directive control of a microstrip array antenna having the little number of column is small, concerning a microstrip array antenna 100 wherein alternative arrangement is performed by making a main line for power supply as a center, distinct radiant quantities are given to antenna element series 6 and 7 connected to a power supply strip line 41, and distinct radiant quantities are given to antenna element series 8 and 9 connected to a power supply strip line 42, so that the flexibility of achievable directivity is enlarged, and low side lobe of the antenna and control of main radiation direction which were difficult conventionally are achieved. Distinct phases are given to the antenna element series 6 and 7 connected to the power supply strip line 41, and distinct phases are given to the antenna element series 8 and 9 connected to the power supply strip line 42, so that low side lobe can be achieved even if an inclined beam is formed from the normal direction of a flat antenna.
