Design of Conformal Antenna for UAVs in 5G Midband for Reliable Coverage

In today’s technological development, unmanned aerial vehicles (UAVs) play a vital role in defense, military purposes, and various civil domains. In UAVs, conformal antennas are in active demand due to their low observability and ability to transform into any shape. In this paper, a conformal antenna was designed to support 5G UAV communication. The proposed antenna has a series-fed design with an even number of dissimilar patches. A novel inset feed is provided between the patches to achieve maximum radiation. The final stage of the patch is designed to allow maximum radiation at 3.13 GHz (mid-band for 5G)with a bandwidth of 33.8MHz. The targeted band’s proposed antenna offers reliable UAV 5G transmission coverage. The antenna performance is analyzed using parameters such as the reflection coefficient (return loss), bandwidths, and E-field and H-field radiation patterns.
