An active phaser based on co-directional couplers is proposed for achieving a flat magnitude transmission while preserving its strong dispersive delay response. The phasers are realized using Half-Mode Substrate Integrated Waveguide (HMSIW) structures, and are successfully demonstrated using full-wave simulations. Due to the non-TEM nature of the device, the proposed phasers are ideally suitable for mm-wave real-Time analog signal processing systems.
