Design of Circularly Polarized Reconfigurable Antenna for Ultra Wideband Applications

Electronics and Communication Engineering,

The advancement in the antenna technology and the growth in high density wireless networks have led to design of antennas with smaller size in dimensions, lower price, lighter in weight ,reconfigurable, multiband and wideband in nature . The study of reconfigurable antennas has made tremendous progress in recent years. This proposed work is an attempt to design an antenna that can dynamically change frequency, pattern, polarization to modifiable structures that can be adapted. Here we have used reconfigurable technique due to which it can be switched among different frequency bands. Ansoft HFSS Software is used for design, simulation and analysis. The design is modified to work for multiband and wideband antenna The antenna is designed to work in 3GHz-7GHz frequencies and is left circularly polarized to avoid losses during communication. PIN diodes have been used to achieve reconfigurability. The results are obtained for the modal driven model . The simulated and measured results are in terms of return loss, gain, radiation pattern and bandwidth are presented.
