This paper proposes the design of multiband repeater antenna with fire-fighting band for in-building mobile communication. The proposed antenna is composed of a center monopole and 4 parasitic elements on a circular plate. In order to realize good reflection coefficients at the multiband, mutual coupling between 4 parasitic elements and center monopole antenna is considered. The important parameters such as distance between parasitic element and a center monopole, and each height of a center monopole and 4 parasitic elements are simulated to obtain good antenna characteristics at the multiband. The diameter of 4 parasitic elements and a center monopole was fixed to 10 mm for easy design and manufacturing. The measurement results of reflection coefficients, 2-D patterns and gain agreed well with their simulation ones.
