“…However, the antenna design is crucial due to the limited opportunity for their deployment and fuselage blocking. Motivated by this, conformal antennas 3 [215], [216] may be considered for the antenna design of aeronautical communications. Furthermore, to accommodate different scenarios, having diverse flight velocities and required throughput, both adaptive coherent/noncoherent and adaptive single/multiple-antenna aided solutions [217] may also be conceived for aeronautical communications.…”

The engineering vision of relying on the "smart sky" for supporting air traffic and the "Internet above the clouds" for in-flight entertainment has become imperative for the future aircraft industry. Aeronautical ad hoc Networking (AANET) constitutes a compelling concept for providing broadband communications above clouds by extending the coverage of Air-to-Ground (A2G) networks to oceanic and remote airspace via autonomous and self-configured wireless networking amongst commercial passenger airplanes. The AANET concept may be viewed as a new member of the family of Mobile ad hoc Networks (MANETs) in action above the clouds. However, AANETs have more dynamic topologies, larger and more variable geographical network size, stricter security requirements and more hostile transmission conditions. These specific characteristics lead to more grave challenges in aircraft mobility modeling, aeronautical channel modeling and interference mitigation as well as in network scheduling and routing. This paper provides an overview of AANET solutions by characterizing the associated scenarios, requirements and challenges. Explicitly, the research addressing the key techniques of AANETs, such as their mobility models, network scheduling and routing, security and interference are reviewed. Furthermore, we also identify the remaining challenges associated with developing AANETs and present their prospective solutions as well as open issues. The design framework of AANETs and the key technical issues are investigated along with some recent research results. Furthermore, a range of performance metrics optimized in designing AANETs and a number of representative multi-objective optimization algorithms are outlined.

“…Comparing with Coax-to-SIW transition, the SIW-to-RWG transition is more stable and can be widely used in millimetre-wave band. A right-angle SIW-to-RWG transition with a single coupling slot or aperture has been introduced [27] and applied to antenna feeding network [6,11,14,15]. Two coupling slots transition has been developed to broad bandwidth [28].…”

In this study, a millimetre-wave slotted array antenna based on double-layer substrate integrated waveguide (SIW) is proposed. The radiating array and feeding network are arranged on different substrate layers with a normal printed circuit board process. The design procedure of radiating elements based on array parameters extraction is introduced. A broadband T-junction and tilted coupling slots are used for power division in feeding network. A broadband right-angle transition between SIW and standard rectangular waveguide WR28 is designed and integrated in the bottom metallic plate for measurement. An 8 × 8 array operating at 35 GHz is designed and fabricated. Measured gain is 19.94 dB with sidelobe suppression of −19.8 dB in the E-plane and −17.7 dB in the H-plane at the centre frequency. The measured bandwidth of 20 dB return loss is 1.32 GHz. The good agreements between simulations and experiments demonstrate that the proposed double-layer SIW slotted array antenna is a good choice for un-rectangular aperture array and large array applications.

A millimeter‐wave cylindrical conformal array with a 120° flat‐top broad beam and a stable 30° downward tilted‐angle is demonstrated, fabricated and measured in this paper. The radiating part consists of eight slotted waveguides, with 32‐element longitudinal slots per waveguide. The feeding network consists of a 1‐to‐8 unequal power divider and a compact phase compensating network, which was designed to provide stable phase differences between the adjacent slotted waveguides for the radiating part. The conformal antenna is wrapped around a cylindrical with a radius of 36.5 mm in the circumferential direction. Measured results show that the beam is covered in H‐plane over a field of view of 120° with a flat‐top, and achieved a stable 30° downward angle in E‐plane. The measured antenna gain was ∼12 dBi with a gain ripple within 1.4 dB. The measured reflection is below −10 dB over the frequency range of 40.25–44 GHz. The proposed new conformal array antenna can be used in millimeter wave wireless local area network. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1666–1671, 2016
