Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

A wideband curved slots antenna established on a substrate integrated waveguide (SIW) technology is presented in this paper for radar and satellite applications. The structure of the proposed antenna is consisting of a microstrip antenna with two curved slots etched on the top of radiation plane and located one on top of the other for bandwidth enhancement. This antenna has been printed on substrate from an FR-4 with εr = 4.3 of and thickness of 1.6 mm. The optimized antenna resonate frequencies are 11.34 GHz and 18.42 GHz with a fractional bandwidth of 500 MHz about (4.409 %) and 4.473 GHz about (24.29 %), respectively. The achieved peak gain is about 6.82 dB and 3.9 dB over the operating frequencies, respectively, this makes it suitable for radar and satellite applications with good matching and return loss characteristics. The design model and performance evaluation of a proposed antenna has been executed by EM simulator, CST Microwave Studio
Internet of Things (IoT) is the development of the Internet and has been acquisition increased attention from researchers, developers in both industrial environments and academic. The hcapacity for communication and data collection possible, providing several opportunities for many IoT applications, particularly medical and healthcare systems. In spite of all the advantages, there are still a lot of open issues that represent the main challenges for Internet of Things, for example information security, privacy, accessibility, portability, and interoperability. IoT provides important characteristics to medical healthcare systems, such as mobility, scalability, and availability that offer an architectural basis for very high technological healthcare applications, such as real-time patient monitoring, environmental and indoor quality monitoring, and ubiquitous and pervasive information access that benefits health professionals and patients. This paper reviews the recent application and the platform architecture of IoT in addition to showing all the challenges and the open issues of IoT. Furthermore, this research synthesizes the existing body of knowledge and identifies the gaps that open up new considerable and challenging future research directions
