A reflectarray element with switchable phase shift for an electronically beam scanning reflectarray operating in the X‐band is presented. The element consists of multilayer printed circuits with a C‐patch coupled to a delay line through a ring slot. The phase shift is obtained by adjusting the length of the delay line. The element integrated with a pin diode to control the phase is assembled and measured in the X‐band. The experimental validations show a wide range of reflection phase with a quasi‐linear phase curve as well as a promising capability of changing the reflected phase between the ON and OFF states of the PIN diode.
