摘要： PROBLEM TO BE SOLVED: To obtain a highly efficient planar array antenna by improving reflection characteristics without inclining a beam.
SOLUTION: A microstrip array antenna has a concave perturbation element 17 on the input side of a radiation antenna element 14. The perturbation element 17 satisfying p1=p2 is provided in a position satisfying θ2-θ1=π, wherein p1 and θ1 are a reflection power and a reflection phase of reflection caused by the radiation antenna element 14 and p2 and θ2 are a reflection power and a reflection phase of reflection caused by the perturbation element 17. Since the reflection caused by the radiation antenna element 14 and that by the perturbation element 17 are canceled by providing the perturbation element 17, the reflection power is minimized. Consequently, the microstrip array antenna is of high efficiency.
