Abstract: : In this paper, a cylindrical dielectric resonator antenna (DRA) excited by two orthogonally placed H-shaped aperture slot is presented with high isolation exceeding 32 dB in C-band. For dual linear polarization, the DRA in its TM110 (HEM11) mode is excited to yield broadside radiation pattern. To confine the slots to the central area of cylindrical DR for TM110 mode, the rectangular shaped slots are molded to H-shaped slots. The co-polarization level in both planes is found to be nearly 30 dB higher than the cross-polarization in broad-side direction. The proposed feed for cylindrical (DRA) has been achieved -10 dB impedance bandwidth of 4.8% for 6.1 to 6.4 GHz. The broadside radiation patterns with nearly same pattern shapes are found to be stable with the gain of 5.2 dB for both ports.
