“…A blade antenna with an oblique side, a 'C' shaped slot and SMA connector has been introduced for the first time in [15] to address these issues. In accordance with [16], the oblique side on the blade allows the antenna to achieve slightly wider impedance bandwidth. Due to constraints on the total height of the antenna in airborne applications, the height of the blade is limited by design to less than 65 mm (λ/4 at 1.1 GHz).…”

This paper is aimed at the characterization and manufacturing of an SMA coaxial fed compact blade antenna with dual frequency characteristics for broadband applications on board of Unmanned Air Vehicles (UAVs). This antenna is linearly polarized, and it combines the benefits of Automatic Dependent Surveillance-Broadcast (ADS-B) and 5th Generation (5G) communications in one single element, covering both the 1.030–1.090 GHz and the 3.4–3.8 GHz bands thanks to a bent side and a ‘C’ shaped slot within the radiation element. Starting from the simulation outcomes on an ideal ground plane, the results are here extended to a bent ground plane and on two UAV commercial CAD models. Details of manufacturing of the antenna in both aluminium and FR-4 substrate materials are presented. The comparison between measurements and simulations is discussed in terms of return loss, bandwidth, gain, and radiation pattern. Results show an antenna with a low profile and a simple structure that can be employed in various wideband communication systems, suiting future UAV assisted 5G networks while being perfectly compliant with forthcoming ADS-B based Detect-And-Avoid (DAA) technologies in Unmanned Aerial Traffic Management (UTM).

“…There are several kinds of antennas for SIGINT use that can be installed in an aircraft. In a practical sense, in the case of a relatively low frequency band, wire-type and blade antennas can be used, while spiral, horn, patch, and aperture or slot antennas can be employed in the middle and high frequency bands [5]. In some cases, a corner or parabolic reflector with an appropriate feeder has been applied as the main antenna when high gain (directivity) is required for long-range or satellite communication.…”

“…In general, the gain is lower in a relatively low frequency range, while a higher gain can be obtained in a relatively high frequency range. For example, a wide band antenna often shows a gain with a negative dBi value in the low frequency band, while a gain with a positive dBi value appears in the high frequency band [5]. The system is designed so that the RF/digital process boards of the receivers are more sensitive or the length of the cable connecting the antenna and receiver is strictly limited.…”

Airborne signal intelligence (SIGINT) systems must be capable of locating radio signal sources. Direction finding (DF) to support this capability is an important factor. There are some practical considerations to be taken when designing the array configuration of a DF system for airborne SIGINT systems. This paper summarizes the practical factors when designing the array configuration of the DF system for airborne SIGINT. In particular, it focuses on four areas: antenna consideration factors when installing the DF system for airborne SIGINT from a practical point of view, array configuration methods for airborne communications intelligence and electronic intelligence, and a numerical analysis to select the optimum antenna position for airborne SIGINT.

“…Conventionally, wideband blade antennas based on the monopole antenna are widely used for aircraft antennas covering the VHF and UHF bands. For example, the modified monopole type blade antenna [2] and the frequency tunable blade antenna [3] were developed. In the case of a low‐profile antenna design, the inverted‐hat monopole antenna [4] and the ferrite‐loaded antenna [5] were reported.…”

Low‐profile inverted‐L aircraft antenna with one folding using ground edge current

A low-profile inverted-L antenna with one folding at 20−90 MHz bands for aircraft applications is presented. The designed antenna is installed on the top of the vertical stabiliser of an aircraft to increase the gain at 20 MHz using the ground edge current and to reduce air drag. The gain of the designed antenna is increased by 3 dB at 20 MHz, and the antenna length is reduced by 41% compared with the reference antenna, which is a folded monopole antenna coupled with a parasitic element. The measured 3 dB return loss bandwidth is 342.9 MHz (51.5%) and the peak gain at 200 MHz is −11.5 dBi for the 1/10 scaled sub-model. In addition, the omnidirectional radiation pattern was observed in the operating frequency.
