For 0 < a ≤ 1/2, we define the quadrilateral zeta function Q(s,a) using the Hurwitz and periodic zeta functions and show that Q(s,a) satisfies Riemann's functional equation studied by Hamburger, Heck and Knopp. Moreover, we prove that for any 0 < a ≤ 1/2, there exist positive constants A(a) and T0(a) such that the number of zeros of the quadrilateral zeta function Q(s,a) on the line segment from 1/2 to 1/2 +iT is greater than A(a) T whenever T ≥ T0(a).
