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.

This study aims to analyze the intention to use on electronic money for Indonesian users. 97 respondents participated in the survey with online survey. 22 hypotheses were formulated and PLS-SEM was used to estimate and test the hypothesized model. The results show that only 8 hypotheses are supported. Lifestyle compatibility and hedonic motivation have a significant direct effect on the adoption of e-money for Indonesian users. It implies that e-money usage is based on the suitability of the product advantages on a daily habit. The customers’ attitude to use e-money only affect by security and hedonic motivation. Furthermore, their trust in e-money is depended on usefulness and social influence while the perceived usefulness can be enhanced the perceived ease to use and lifestyle compatibility of the product
A new compact 85 x 55 x 1.6 mm3 multiband reconfigurable 4x1 MIMO antenna is proposed for cognitive radio applications. The proposed structure consists of four elements reconfigurable communicating antenna and ultrawide band UWB sensing antenna in the same substrate. The frequency reconfigurability range of the communicating antenna from 7.5 to 15.5 GHz, while the UWB sensing antenna operates with a band from 2.7-23.2 GHz that can cover the entire UWB band from 3.1 to 10.6 GHz. The proposed antenna is optimized using Genetic Algorithm to operate on four resonant frequencies of 8.1 GHz, 12 GHz, 13.95 GHz, and 15 GHz that are used to cover various wireless applications such as WiMAX, international telecommunication union (ITU), satellite, Radar, and broadband applications. The frequency reconfigurability is achieved using only single RF switch (PIN diode) for frequency tuning. The results introduced maximum gain of 7.7 dBi, return loss ≤ -20 dB, Envelope Correlation Coefficient ECC ≤ 0.015, and Isolation ≤ -15 dB. The proposed antenna has been designed and optimized using CST software and it has been fabricated and presents good agreement between the simulated and measured results
