—In this paper, a half-split cylindrical dielectric resonator antenna (HSCDRA) is designed for first person view (FPV) application. Proposed antenna is designed with characteristics including a wideband bandwidth and circular polarization nature. As for the structural information, antenna consist half split cylindrical dielectric resonator (HSCDRA) with two different layers of permittivity while considering radial direction of projection. The circular polarization is achieved by exciting the purposed antenna through a modified CPW (coplanar waveguide) with slotted patch. For the confirmation of rotation of electric field, a TM11 mode is used to excite inside the DRA structure. Proposed antenna radiates predominantly in right hand circular polarization field with - 12dB over the working band. Center frequency of 5.5 GHz is used which results in 850 MHz usable bandwidth where both S11< -10dB and Axial Ratio (AR) < 3 dB, with bandwidth falls in the range of 5.15 - 6.00 GHz, also radiation efficiency is found to be 90%.
