DESIGN OF FREQUENCY RECONFIGURABLE PATCH ANTENNA FOR WIRELESS APPLICATIONS

Abstract

Frequency reconfigurable slot antenna is employed for wireless application to work in a very multi
bands. The previling system has several problems like less radiation potency, cross polarization at
high frequencies. During this project we have a tendency to are overcoming with these problems like
dynamical the substrate material of the antenna to be made-up. The world of antenna is additionally
reduced to create it additional compact so it is wide employed in all wireless applications. All the
paramaeters of the antenna are measured and compared with the prevailing one. The projected
system has higher radiation potency compared to current system. All characteristics are improved
compared to the prevailing system. Cross polarization doesn’t occur in high frequencies that create
this antenna to work in higher frequency ranges, so the direction of output radiation does not
modified in high frequency. The gain of the antenna additionally exaggerated relatively.
