PROBLEM TO BE SOLVED: To provide a collinear antenna which can reduce assembling time and number of components, and is low in cost and high in gain by using microstrip structure instead of coaxial structure and printed circuit board structure. SOLUTION: An antenna element A and an antenna element B in which wide antenna radiation elements and narrow feeding elements are alternately arranged are arranged at a predetermined interval so that the antenna radiation elements of the antenna element A face the feeding elements of the second antenna B, and the antenna radiation elements of the antenna element B face the power supply elements of the antenna element A. In addition, a spacer 5 for holding the antenna element A and the antenna element B is arranged in the middle of the longitudinal directions of the antenna element A and the antenna element B.
