摘要

In this paper, an antenna is designed for Unmanned Aerial Vehicles (UAV) based First-Person View (FPV) applications. Present day antenna technology for UAV is based on dipole antenna, but there are numerous disadvantages like shorter range, synchronization difficulties, multipath effects, etc. To overcome these drawbacks, a Dielectric Resonator Antenna (DRA) is designed. There is large flexibility for shape selection for DRA, and the shape selected is Half Split Cylindrical (HSCDRA). The proposed antenna consists of double-layered cylindrical DRAs with Co-Planar Waveguide (CPW) feeding technology with a slotted patch. The simulation of the proposed antenna using HFSSv15.0.3 reveals that the radiation is predominantly left-hand circular. For a center frequency of 5.8 GHz, the bandwidth attained is 450MHz, S11< -10dB and Axial Ratio (AR) <6dB, with a radiation efficiency of 78%.
