“…Over the past decades, various phase shifters based on substrate integrated waveguide (SIW) have been implemented in different technologies such as liquid crystal (LC), ferrite low‐temperature co‐fired ceramic (LTCC) and varactor diodes as a tuning component to provide continues phase shift [1–7]. In [2] by partially replacing the dielectric substrate of SIW with LC and embedding an electric bias structure, an electronically tunable phase shifter is developed.…”

“…By changing the

between the SIW‐slot and the HDC slab, the electric field intensity of the slot mode varies and creates the phase shift. The magnetic actuator is used to control the position of HDC slab as a tuning component to realise continuous phase shift [6, 7]. Design and analysis of continuously tunable SIW phase shifter with wide phase shift range and low power consumption is the main topic of this Letter.…”

A continuously tunable phase shifter based on a substrate integrated waveguide (SIW) is proposed for high-performance applications at millimetre-wave frequencies. The proposed phase shifter consists of two slots cut on the SIW's broad wall and a high dielectric constant (HDC) slab over the slots. The phase shifting mechanism is based on perturbing the electric field of the SIW-slot by putting a HDC slab over two slots. The fabricated phase shifter exhibits linear phase-frequency response behaviour with an average insertion loss less than 2 dB over a phase shift range of 360°in the operating frequency band (29-31 GHz).
