Abstract
A reconfigurable antenna built on E-shaped structure with an ability to control bandwidth is discussed in this proposed work. To configure antenna automatic or manual tuning is done so that they can accustom to the varying system requirements thus can avoid those limitation and offers extra functionality. A frequency reconfigurable E-shaped patch antenna can be utilized for improving the bandwidth. The bandwidth can cover the frequency range from 1.85 GHz-2.33 GHz. The enactments of the offered antenna, in terms of reflection losses and radiation patterns, with divergent DC bias voltages is analyzed using a varactor diode. A broad research was taken over to analyze the nature of the antenna at different frequency.
