چکیده
|
A novel geometry of polarization and frequency reconfigurable antenna is proposed in this paper. proposed antenna consists of an l shaped patch antenna, where arms are separated using pin-diode. two parasitic elements, shorted back element and edge tapered defected ground structure with slot are used for achieving wide impedance and axial ratio bandwidth. it acts as circular polarized antenna with 1.183 ghz axial ratio band width and 3.09 ghz impedance bandwidth in on state of both diodes and act as linear polarized frequency reconfigurable antenna at remaining states of diodes. proposed antenna can be used in c band wireless applications like radar, satellite communication etc.
