A Double T Shaped Reconfigurable Antenna for Ku-Band and K-Band Applications

In this paper, a Reconfigurable Antenna has been proposed. This antenna has a feature of two diodes working in the off and on states respectively. The proposed antenna works in the K-Band in the off state and in the Ku-Band as well as in the K- Band in the on state. The two diodes exhibit different characteristics while working in the on state as well as in the off state. This takes into account four results with two diodes off and two diodes on as well as with one diode on and the other diode off. These different states show different radiation patterns, different frequencies as well as different gains at different frequencies. When the diode is transformed from the off state to the on state, one resonant frequency splits into three other resonant frequencies. This antenna works in the range of 10 GHz-30 GHz.
