In this paper the design and implementation of a two-element antenna array using the substrate integrated waveguide (SIW) technique and operating at 10 GHz is presented. The phase shifter was designed first and it consists of an SIW section where two inductive posts are inserted. The phase shifting is achieved by changing the position of these two inductive posts inside the structure. The second element designed was the SIW banana-shaped slot antenna. These two elements were then assembled to form the two-element antenna array. Numerical simulations and experimental measurements on prototypes were carried out for two differential phases between the array elements, namely 0 and 22.5. Results showed a fairly good agreement. In fact, a reflection coefficient of better than 13 dB was obtained around 10 GHz. The E-plane radiation pattern showed a beam shift of 22, with a maximum gain of more than 8.7 dB, and demonstrated the possibility of designing an SIW antenna phased array.
