Abstract
In this research, a radiation pattern reconfigurable (RPR) based multiple antenna was designed using a compact combination of a driven element and parasitic elements that operates at 3.5 GHz. The proposed antenna has the ability to change the radiation behavior to serve the user with better performance. The radiation characteristic of the antenna, especially the tilt angle could be reconfigured with the use of RF switches. The multiple antenna was designed on 94.4 mm x 110 mm Rogers substrate. First, an RPR antenna that uses parasitic patch array antenna was designed as a single element. Then this RPR was deployed as 2 x 1 RPR MIMO antenna using two types of configurations. Finally, the analysis showed that the multiple antenna arrangement using configuration II provides better results in terms of steering angle and gain.
