The proposed fully metallic, low profile, and high-performing antenna offers wideband operating bandwidth, which makes it suitable for space applications. To achieve circular polarization, an array of circular holes is perforated at an offset position from the narrow wall of the WR-10 waveguide. The prototype antenna provides a wide axial ratio bandwidth of 13% and an average half-power beamwidth of 4.5° on the elevation plane. At high frequencies, the thickness of the slot affects the emission through the slot, which is not typically encountered at low frequencies. Therefore, to increase the magnitude of the radiated power, the wall thickness of the hole is reduced. The proposed circular hole slotted waveguide antenna design provides superior tolerance, accuracy, and precision compared to any other structures. These characteristics eliminate fabrication challenges, especially within the W-band, and can seamlessly extend into the sub-THz domain as well. The proposed antenna is robust, easy to fabricate, and appropriate for integration into CubeSat. It can be adapted for W-band CubeSat LEO, intersatellite, and constellation missions.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"6 1","pages":"19-26"},"PeriodicalIF":0.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fortunately, these communication security challenges can be transformed into path-planning problems that minimize the weighted sum of UAV mission time and transmission outage time. In order to design the complex communication environment faced by UAVs in actual scenarios, we propose a system model, including building distribution, communication channel, and antenna design, in this article. Besides, we introduce other UAVs with fixed flight paths and ground interference resources with random locations to ensure mission UAVs have better anti-interference ability. However, it is challenging for classical search algorithms and heuristic algorithms to cope with the complex path problems mentioned above. In this article, we propose an improved deep deterministic policy gradient (DDPG) algorithm with better performance compared with basic DDPG and double deep Q-network learning (DDQN) algorithms. Specifically, a post-decision state (PDS) mechanism has been introduced to accelerate the convergence rate and enhance the stability of the training process. In addition, a transmission outage probability experience memory (TOPEM) has been designed to quickly generate wireless communication quality maps and provide temporary experience for the post-decision process, resulting in better training results. Simulation experiments have proven that, compared to basic DDPG, the improved algorithm increases training speed by at least 50 %, significantly improves convergence rate, and reduces the episode required for convergence to 20 %. It can alsohelp UAVs choose better paths than basic DDPG and DDQN algorithms.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"6 1","pages":"2-18"},"PeriodicalIF":0.0,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With evolving requirements of heterogeneous services in future wireless networks, it is challenging to realize on-demand resource management and network deployment in UAV-assisted MEC systems. This article investigates unified communication and computation resource management as well as network deployment to meet the quality of service (QoS) of enhanced mobile broadband (eMBB) and massive machine-type communication (mMTC) simultaneously. A network utility minimization problem is formulated which jointly considers UAV deployment, user association, spectrum slicing, communication, and computation resource allocation. First, a coalition game-based UAV deployment and eMBB user (eUE) association algorithm is designed, based on which a communication and computation resource allocation algorithm is devised by convex optimization. The mMTC user (mUE) association and power control is optimized via successive convex approximation. Then, a spectrum slicing and allocation algorithm is designed by the bisection search method. Finally, a joint resource allocation and network deployment scheme is proposed. Simulation results demonstrate that our proposed algorithm can effectively reduce average service delay of eUEs and increase the number of served mUEs in UAV-assisted MEC systems.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"6 2","pages":"133-143"},"PeriodicalIF":0.0,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144179169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Uncrewed aerial vehicles (UAVs) and nonorthogonal multiple access (NOMA) technology enable the MEC networks to provide offloaded computing services for massively accessed terrestrial users conveniently. However, the broadcast nature of signal propagation in NOMA-based UAV-MEC networks makes it vulnerable to eavesdropping by malicious eavesdroppers. In this work, a secure offload scheme is proposed for NOMA-based UAV-MEC systems with the existence of an aerial eavesdropper. The long-term average network computational cost is minimized by jointly designing the UAV’s trajectory, the terrestrial users’ transmit power, and computational frequency while ensuring the security of users’ offloaded data. Due to the eavesdropper’s location uncertainty, the worst-case security scenario is considered through the estimated eavesdropping range. Due to the high-dimensional continuous action space, the deep deterministic policy gradient algorithm is utilized to solve the nonconvex optimization problem. Simulation results validate the effectiveness of the proposed scheme.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"6 2","pages":"113-124"},"PeriodicalIF":0.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144178862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, ensuring reliable communication remains a great challenge, particularly in environments characterized by weak signals or high levels of electromagnetic interference. To tackle this challenge, this study presents a design and optimization approach for a miniature UAV antenna. This antenna achieves significant performance improvements by optimizing the magnetic field (MF) distribution and convergence within its central section. Specifically with the aim of capturing and amplifying signals in a specified direction, the antenna enhances reception sensitivity, especially in challenging operational settings. The structure ensures robust and consistent signal reception with a maximum gain of up to 12.8 dB and a converging MF magnitude of 2279 A/m at its center. Furthermore, it operates effectively within the C band, exhibiting a relative bandwidth of 12.2%. This capability empowers UAV to transmit reconnaissance data accurately and swiftly, regardless of the distance traveled or the complexity of the electromagnetic environment.

To address this problem, this article proposes a strategy to achieve a better tradeoff between accuracy and robustness, which mainly consists of symbol perturbations and examples mixing. First, we employ a symbol processing approach for randomly generated initial perturbations, which makes model identify the correct parameter attack direction faster during the training process. Second, we put forward a methodology that utilizes a mixture of different examples to generate more distinct adversarial features. Further, we utilize scaling conditions for tensor feature modulation, enabling the model to achieve both improved accuracy and robustness after learning more diverse adversarial features.
