A low‐profile dual‐mode antenna for unmanned aerial vehicles applications

Abstract: A low‐profile dual‐mode antenna is proposed in this paper. The antenna is composed of a semi‐rectangular‐annular (SRA) coaxial line with sleeve loading structures vertically mounted on the ground plane. The proposed antenna has two radiation modes, mode 1 of the vertically polarised (VP) radiation characteristics at 500 MHz and mode 2 of the horizontally polarised (HP) radiation characteristics at 588 MHz. The two vertical components of the SRA coaxial line contribute to the VP radiation, which is achieved wit… Show more

“…In addition, antennas used in UAVs application needs to possess vertical polarization and horizontal omnidirectional radiation pattern to ensure communication with ground controllers. [5][6][7] Considering the constraint of the loading and the requirement of the aerodynamics of UAVs, antennas applied to UAVs need to be lightweight, low-profile, and small in lateral size. Many low-profile vertically polarized antennas have been published.…”
