“…In addition, creating slots in the outer sides of the patch that surrounds the cone showed significant effects on the antenna bandwidth and achieved a 97% fractional bandwidth [18]. Another approach by adding a top hat with different shapes to the cone is reported to achieve better matching between the antenna and the feeder at the lower band [19][20][21][22]. A lightweight monocone antenna integrated into a hollow cavity is also reported and showed the trade-off between the cavity size and the antenna [23].…”

In this paper, a capacitively-fed, ultra-wideband (UWB), and low-profile monocone antenna is proposed for vehicle-to-everything (V2X) applications. The proposed antenna consists of a monocone design with an inner set of vias. Additionally, an outer ring is added with a small gap from the monocone and shorted with six folded wires of different lengths to extend the operating band. The proposed antenna covers the frequency range from 0.75 GHz to 7.6 GHz and has a 164% fractional bandwidth, with a gain value varying between 2 and 10 dBi. The dimensions of the antenna are 0.37λL × 0.37λL × 0.067λL. The antenna was fabricated using a 3D printer with low-cost polylactic acid plastic (PLA) material and then sprayed with aerosol copper nanoparticles. The efficiency was approximately 90% throughout the frequency bands of interest. Finally, the proposed antenna was installed on a vehicle and tested with an OBU (onboard unit) and a RSU (roadside unit) in the field. The results show a longer wireless communication range for V2X applications.

“…In particular, inverted-hat antennas (IHA) [12][13][14] can meet the specific requirements of DME applications. Notably, several previous works show the significance of the monocone antenna and IHA size and shape on VSWR, bandwidth, radiation patterns, and gain [15][16][17][18][19][20][21].…”

Antennas installed on aircraft are used for communications as well as for various radio navigation systems such as direction finders, distance measuring systems, and altimeters. Generally, these systems use blade antennas operating in the L frequency band. Recently, inverted-hat empty section monopole antennas have been found to be good candidates for such uses. In this study, we propose a new design of inverted-hat antenna based on optimized elliptical shapes and a filled cavity. The dielectric material added in the cavity helps to improve the monopole stability and to adjust the resonant frequency of the antenna. The proposed antenna meets the distance measuring equipment requirements, namely an omnidirectional radiation pattern in the H-plane, a vertical polarization, a frequency band from 960 MHz to 1.22 GHz, and a gain better than 1 dB. This antenna is entirely made of aluminum in order to obtain a homogeneity with the aluminum fuselage. In addition, the solution proposed brings a better protection against weather conditions. The antenna performance is analyzed on the basis of simulation and measurement results.
