Abstract
The reconfigurable antenna provides on-demand services over the present and future communication applications with the help of a RF switches. The features of reconfigurable antenna are offering multiple resonant frequencies depending on the mode of the antenna. The switching is not only possible from one resonant frequency to another; it is also possible to switch from one polarization to other polarization, i.e., circular polarization to linear polarization. This paper discusses about the basic features of microstrip antenna re-configurability, power efficiency, polarization, multipath, inference, fading, and RF distortion. Additionally, the paper describes several key topics related to RF MEMS switch-based reconfigurable patch antenna material analysis. This paper surveys the role and challenges of RF MEMS switches based reconfigurable patch antennas. A little discuss is extended on the PIN diode-based reconfigurable antennas.
