Substrate integrated waveguide (SIW) technology is widely known transmission line technology adapted for use in various types of microwave circuits. This article deals with the analysis and design of a phase shifter based on the SIW technology. With simulation and measurement results obtained from the phase shifter with using air holes inside the structure, a test circuit was designed and manufactured. Results show that a phase balance of less than 10° is achieved with the experimental setup. The return loss value is better than 15 dB for working frequency band 8.85 GHz − 9GHz. The main benefit of this work is the easy of implementation air holes inside the structure and also the easy of manufacture of the circuits for antenna arrays, where a certain number of identical circuits is usually needed.
