Design of Frequency Reconfigurable Slot Antenna for Wireless Applications

Abstract

 Frequency reconfigurable slot antenna is used for wireless application to operate in a multi bands. The existing system has many issues like less radiation efficiency, cross polarization at high frequencies. In this project we are overcoming with these issues like changing the substrate material of the antenna to be fabricated. The area of the antenna is also reduced to make it more compact so that it can be widely used in all wireless applications .All the parameters of the antenna are measured and compared with the existing one. The proposed system has better radiation efficiency compared to current system. All characteristics are improved compared to the existing system. Cross polarization does not occur in high frequencies which make this antenna to operate in higher frequency ranges so that the direction of output radiation does not change in high frequency. The gain of the antenna also increased comparatively.
