A Dual Band Rectangular Patch Antenna for 5G Applications

This paper presents a rectangular-shaped microstrip antenna that resonates at dual frequencies, 33 GHz & 46 GHz. The model was simulated using the Computer Simulation Technology software and focuses on attaining a return loss rate lower than -10dB. The suggested Rectangular Patch Antenna (RPA) is designed using a Rogers RT 5880 substrate. The RPA will implement the technique of air cavity, alongside a substrate of thick-film to achieve high-gain. The RPA’s structure includes a transmission line that improves the antenna’s radiating ability between 30 and 50 GHz out into open space. There are 2 different models suggested and simulated in this work. First a simple RPA is designed and analyzed. Following it an enhanced schematic that utilizes the air cavity was proposed and analyzed. The distinctive design aims to reach a gain that’s above 5db, covering around 1 GHz bandwidth at each frequency and directivity of 6dbi. The results and comparison prove that the suggested RPA is a promising candidate for the 5G millimeter applications.
