Abstract :
A 2×4 Ku-band cavity-backed microstrip patch antenna array has been implemented using the substrate integrated waveguide technology (SIW) -a low cost multi-layer PCB process. Cavities are emulated using vias and the patches are probe fed using a microstrip feed network. The microstrip feed network is placed in the back of the antennas to reduce the mutual coupling between the feed network and the patches. Therefore, a superior antenna performance was obtained in terms of the realized gain and the radiation pattern. The array was fabricated and its measured results agreed well with our theoretical predictions and indicated high efficiency and wide bandwidth of greater than %74 and 6% respectively.
