Abstract :
This paper presents a method for the integration of dielectric resonator antenna (DRA) array with substrate integrated waveguide (SIW) arranged in sequential rotation configuration. The proposed antenna structure is symmetric, low loss and compact. Linear-polarized (LP) DRA elements are used as loads to a hybrid junction SIW splitter to generate high purity circular polarized (CP) radiation. The simulation results show a symmetric radiation pattern of very low cross-polarization and 1 dB axial-ratio band width of ~ 1GHz at 36.50 GHz.
