Abstract Many advanced learning algorithms using computational intelligence are being developed which work in accordance with the environment. Batteries play a crucial role as main stopper for using wireless communication in the industry. It has been proved that waste energy is produced during the industrial activities. In this work we studied the possible components of Internet of Things devices and identified... Read More

Abstract Speech processing and voice modelling activities are important where the speaker identification plays a role. The critical security systems depend on the speaker definition application. The main issue is the large scale voice recognition. Rapid and new techniques use computational intelligence for speaker database construction. For speaker identification attempts have been initiated for the establishment of variable-based systems and the... Read More


The Study of Design Features of CPW-FED Asymmetrical Slot Array for K-Band Applications

Marija Milijic, Branka Jokanovic

https://doi.org/10.6025/stj/2020/9/2/56-62

Abstract We in this work discussed the design features of antenna array that consists rectangular slots positioned asymmetrically relative to CPW feeding line. The designed asymmetrical slots offer greater flexibility in antenna design and easier control of crucial antenna parameters such as gain, side lobe suppression and bandwidth. Besides we designed it to be useful for frequency range 24.25-27.5 GHz and... Read More
