Consider a point with the point z, located on the positive z-axis. The ring has a radius a. An electric field vector originating from an element of charge on the ring makes an angle θ with the z-axis. 

The electric field vector can be decomposed into two components. One component points in the positive z-axis. The other component points parallel to the radius.
