Pentagon slot resonator frequency reconfigurable antenna for wideband reconfiguration

With the advances in the field of communication and the current state of affairs in the development of antennas the need of compact multiband, multifunctional and cost effective antenna is increased. The study of reconfigurable antennas has made great progress in recent years. They are lighter in weight, smaller in dimension and lower in price. Again, the reconfigurable antennas can offer variety of features like change in operating resonant frequency, polarization, and radiation pattern. As a result of the significance of frequency reconfigurable antennas, along with extensive literature survey a microstrip antenna is taken as basic structure. A pentagon resonator slot is chosen and its simulation and fabrication is carried out. This paper presents new design of slot resonator with fabrication result. The design is modified to work for multiband and wideband antenna. The reconfiguration is done using Pin diode to switch between multiband and wideband.
