Abstract

In this study, optimization techniques applied in designing microstrip bandpass ultra-wideband (UWB) filters are presented. Optimization based on various defected ground structure techniques, resonator designs, and type of dielectric materials is discussed. Microstrip bandpass filters implemented at UWB frequency bands used in wireless communication systems have key features to control frequency response in passband and stopband. Optimization techniques are studied to attain optimum performance of bandpass microstrip filters to ensure minimum insertion loss, high selectivity, compactness, sharp transitions at cut-off frequencies, high return loss, and excellent linearity. Extensive study shows that proper selection of fabrication techniques and type of material optimizes the performance of microstrip filter design, thereby increasing its practicability for emerging wireless communication systems.

Abstract

This study examines the watch ownership patterns, preferences, and usage habits among individuals in Ahmedabad, with a focus on demographic factors such as age and gender. Using a sample of 106 respondents, data were analyzed to explore correlations between demographic characteristics and preferences for various watch types, including traditional, digital, and smartwatches. Results indicate that younger respondents, particularly those aged 18-25, show a strong preference for digital and smartwatches due to their multifunctional capabilities. Gender did not significantly impact watch ownership or type preference, suggesting a broadly inclusive appeal across demographics. This research highlights the shift toward multifunctional wearable technology and offers insights into the future scope of the wearables market, which is poised for further growth and adaptation. The findings contribute to a better understanding of consumer trends in wearable devices, particularly in the context of changing technological and lifestyle demands.
