Design, simulation, and analysis of microstrip patch antenna for wireless applications operating at 3.6 GHz
In this study, a microstrip patch antenna that works at 3.6 GHz was built and
tested to see how well it works. In this work, Rogers RT/Duroid 5880 has been
used as the substrate material, with a dielectric permittivity of 2.2 and a thickness
of…

Intelligent alarm system for hospitals using smartphone technology
During the last decade, attention was paid to detect the accident and call
the ambulance as soon as possible, the situation was neglected after the arrival of the patient to the specified service point. This negligence led to
an increase in the…
