“…10 Additionally, antennas should be not only low-profile but also compact in size and light. 11 Low-profile antennas with omnidirectional radiation have been much studied, [12][13][14] including an L-shaped monopole antenna loaded by a shorted pin, 12 a folded monopole antenna with capacitively coupled parasitic elements, 13 and a shorted top hat monocone antenna 14 ;…”

A wideband low‐profile miniaturized segmented loop antenna is proposed in this letter. The antenna consists of a segmented loop comprising 4 segments with stubs, a shorting strip, and a patch element. The antenna is miniaturized by reducing the number of segments and by adding stubs. At 956 MHz, the antenna has an improved impedance matching by using the shorting strip, and an omnidirectional radiation due to coupling between the overlapping areas of the segments placed on the top and bottom of the substrate. In the high frequency band, the antenna has a wide −10 dB reflection coefficient bandwidth covering 3700 MHz WiMAX, 5200 MHz WLAN, and 5800 MHz WLAN with a quasi‐omnidirectional radiation characteristic.

“…In particular, the antenna mounted on a UAV has to have a low profile and be lightweight to meet the aerodynamic requirements and the limits of payload capacity, respectively. To attain these requirements, several low‐profile antennas for UAV were proposed . Although these antennas have an omnidirectional radiation pattern, have a low profile, and are light weight, their bandwidth is not wide enough for UAV applications.…”

“…Other low-profile antennas suggested have a narrow bandwidth. [10][11][12][13][14][15] In the present study, an antenna was designed by focusing on three important points. First, the antenna should be able to cover a band wider than the bandwidth of conventional antennas for signal detection.…”

In the present study, ultra‐wide band antenna attachable on unmanned aerial vehicle (UAV) surfaces usable as signal detection antenna in various bands was designed, and the practicality of the developed antenna was verified by attaching the antenna to a UAV and measuring the performance. The antenna suggested in this article was manufactured by forming a hemispheric conductor having the shape of a baseball seam on the ground and satisfying a self‐complementary through an image theory. This Hemispheric shape can reduce a drag and risk of breakage. The diameter of the antenna is 400 mm (0.4λL and λL is 0.3 GHz.), the height is 200 mm (0.2λL), and the ground size is 800 mm (0.8λL) × 800 mm (0.8λL). The designed antenna showed an ultra‐wide band property as it was matched to a band from 300 MHz to 10 GHz. After being attached to the bottom of a 7.3:1 scale UAV, the antenna showed matching properties from 1.85 to 10 GHz above and maintained a monopole pattern in all directions and in a bandwidth. To author's knowledge, the antenna was proper to using as a signal detection antenna which need wide bandwidth, conical pattern, drag reduction and reduced risk of breakage.
