Parabolic reflectors have very good directivity. However, when put behind a partially reflecting surface, they suffer from destructing in‐phase rays and they experience deteriorated characteristics. In this work we consider fixing this impediment and we enhance the low profile by providing a new approach based on ray optics model. This approach grabs the equations of multiple reflections between the...
In this paper, we are interested in designing a prefractal dual-band antenna for RFID (Radio Frequency IDentification) systems at 2.42 GHz and LTE (Long Term Evolution) systems at 3.5 GHz. We mainly focus on the optimization of the structure's diffraction behaviour by generating parameterized structures to help automation of the multi-objective optimization. Custom macros were developed using commercial...
