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.

Advances in tech geared targeted at moving the society to a higher plain and sophistication with ease. The further integration of Internet to ease resource dissemination is attributed to its usage ease, ubiquity in its nature, low transaction cost and trust in channel. All these will continue to advance its popularity, usage ease and adoption. The rise thus, in adversaries threatens data integrity – and the task of detecting and use of countermeasures against intrusion remains a continuous task. Our study use a convolution neural network deep learning model to detect intrusion activities. Results shows model accurately detects malicious from genuine uncompromised packets traffic with confusion matrix yielding: TP = 43, TN = 3, FN = 5, FP = 9 for model sensitivity, specificity and accuracy. Model also displays a sensitivity of 93%, specificity of 25%, accuracy of 97% with a misclassification error rate of 4% for data inclusion that were not originally used to train model.
In a wireless communication system, one component that plays an important role is an antenna. On the radar system, it takes the characteristics of low profile and lightweight antennas. So, the current technology trends have focused a lot on the design of printed antennas. The type of printed meander dipole antenna was chosen because it was able to reduce the dimensions of the usual dipole arm. In this paper, the authors designed and simulated the antenna using CST Studio Suite. Then we fabricated and measured both a single element and eight-element antennas to verify the antenna performance. The antenna works at S-Band frequency. This antenna using Rogers RO-4003C (lossy) as a substrate with relative permittivity 3.55, thickness 1.524 mm, and has the advantage of being more resistant to input power (power handling) than FR-4. The realization of eight-element antennas is using for a 3-dimensional monopulse tracking air surveillance radar. The simulation results show functional return loss that is less than -15 dB. The radiation pattern is directional. Single element gain is more than 5 dB, while eight elements gain 13.78 dB, and the antenna input impedance is 50 W. So, the antenna has been qualified to the desired specification and can be used as a reference antenna for air surveillance radar system.
