“…Figure 7 shows the antenna normalised directivity pattern, from FEKO and anechoic-chamber measurements, for four selected frequencies from 850 MHz to 5.05 GHz. As can be seen, both conductive paints match the results given by the FEKO simulations and the far-field directivity in [4]. The antenna omnidirectional pattern is observed, as expected, by referring to the radiation pattern variation with φ in Figure 8.…”

A 3D-printing technique, combined with conductive paints, is investigated for a lowcost methodology in antenna design. The technique is applied on a conical antenna of 41 • above a ground-plane using carbon and nickel-based conductive paints. An impedance bandwidth of 20:1 is achieved. Measured normalised-directivity patterns correlate with simulations and the antenna is more than 90% efficient up to 5 GHz.

“…1,7 Antennas with communication capabilities are often utilized in various types of aviation equipment in different structural shapes. In the past design of airborne applications, antennas with different structures, such as segmented loop printed antenna, 13 wireframe monocone antenna, 14 and improved monopole antenna, 15 where the monopole antenna due to its volume Small, lightweight, and able to utilize the airborne environment as its ground plane are becoming more common. The knife monopole antenna 16 is chosen for aerial applications due to its low windage, lightweight, simple construction, and wide bandwidth.…”

The letter presents a low‐windage omnidirectional antenna for high‐speed aircraft in the UHF and L bands. It combines a planar biconical antenna with a printed tape parasitic branch monopole antenna. Upgrading the traditional restricted‐length biconical antenna to a double‐layer planar design meets the compact, lightweight, and low windage requirements of airborne use. To enhance bandwidth and meet the lightweight, compact criteria of high‐speed aircraft, the planar‐printed monopole antenna integrates parasitic stubs and loop antenna concepts. Experimental results exhibit excellent isolation between antenna elements, with over 15 dB segregation and operational spectrum return loss of 27% and 18% at 10 dB. The voltage standing wave ratio is below 2, with less than 5 dB variation in the horizontal radiation pattern across frequency bands. The antenna, measuring 20 mm × 190 mm × 270 mm and weighing around 0.5 kg, holds great promise for high‐speed aircraft applications.

“…With regard to antennas, general unidirectional antennas such as patch type and horn type antennas can be easily embedded within the fuselage of an aircraft via conformal design. Omnidirectional radiation antennas for aircraft applications, monopoles, wire‐frame monocones, helical, blades, log periodic arrays, and dipole array antennas have been reported . Protruding antennas should be aerodynamically designed and installed onto aircraft fuselage to avoid potential deteriorations to performance.…”

A flush‐mounted monopolar patch antenna for unmanned aerial vehicle (UAV) applications is proposed. To establish vertical monopole‐like radiation characteristics with a low‐profile on the fuselage of a UAV, a TM21 higher‐order mode circular patch antenna (HMCPA) was proposed. For practical installation on the UAV, the HMCPA was embedded into a round recess within the UAV fuselage and was covered by a 3D printed radome with polycarbonate nuts and bolts. The flush‐mounted HMCPA had an aperture radius of only 0.23 λ0 and a height of 0.02 λ0 at 700 MHz. To verify the practicability and performance of the antenna, characteristics of the proposed HMCPA were compared with those of a λ0/4 monopole via simulation. Additionally, antenna performance was analyzed when attached to a full scale UAV model. The proposed HMCPA featured monopole‐like radiation characteristics with a low‐profile at 700 MHz. The measured fractional −10 dB reflection coefficient bandwidth and peak gain were 6.46% and 1.86 dBi, respectively. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1202–1207, 2017
