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 with the in‐phase electric currents on the two vertical components by adjusting the length of the in‐body inductive loading structures. The horizontal component of the SRA coaxial line is mainly contributed to HP radiation when the electric currents on two vertical components are reversed. And the antenna is well matched with the additional impedance matching network, which consists of two inductors and a capacitor. The height of the fabricated prototype is only 25.9 mm (about 0.04λ) at 500 MHz. The fabricated prototype possesses monopole‐like radiation pattern at 500 MHz and loop‐antenna‐like radiation pattern at 588 MHz. The measured maximum gain of the proposed antenna at 500 MHz is −6.8 dBi, and the measured maximum gain of the proposed antenna at 588 MHz is 2.5 dBi. The antenna is suitable for unmanned aerial vehicles communication systems due to its advantages of low‐profile and dual‐mode radiation.

“…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.…”

A dual-frequency inverted-F antenna operating in the ultrahigh frequency band is presented. The proposed antenna includes an inverted F-shaped radiator and a dual-frequency loading circuit. The dual-frequency loading circuit is located between the short pin and the ground. The dual-frequency loading circuit presents a short-circuit state at the low-frequency band and an open-circuit state at the high-frequency band. By introducing the dual-frequency loading circuit, the proposed antenna possesses dual-frequency performance compared with the traditional inverted-F antenna. The resonant frequencies of the proposed antenna can be controlled by adjusting the component values of the dual-frequency loading circuit. A prototype was fabricated and measured to validate the method.The height of the fabricated antenna is 40 mm at 713 MHz. The bandwidths of the fabricated prototype are 713-779 MHz and 858-920 MHz. The proposed antenna possesses vertical polarization, which shows that the proposed antenna has broad application prospects in unmanned aerial vehicles communication systems.
