摘要

Design of a reconfigurable multiband multi polarized monopole antenna with simple bias circuit is presented. The proposed antenna consists of simple radiating truncated rectangular patch with a cross-shaped slit and a ground plane embedded with L-shaped slit. The antenna produces two separate impedance bandwidth with three senses of polarization namely right hand circular polarization, left hand circular polarization and linear polarization. PIN diode is used to reconfigure the L-shape slit in the ground plane. The antenna generates dual band behavior with multiple circularly and linearly polarized bands. With OFF state of the diode, the impedance bandwidth of the antenna is 10.22% and 83.43% from 3.99?GHz to 4.42?GHz and 5.84?GHz to 14.20?GHz, respectively, while 3-dB axial ratio bandwidths are 9.83% and 13.73% from 5.79?GHz to 6.39?GHz and 8.49?GHz to 9.74?GHz, respectively. In the ON state, antenna also shows the dual band behavior with an impedance bandwidth of 49.10% and 21.31% from 7.20?GHz to 11.04?GHz and 12.66?GHz to 15.37?GHz, respectively, while 3-dB axial ratio bandwidth of 6.49%, 8.45% and 2.0% from 7.90?GHz to 8.43?GHz, 10.08?GHz to 10.97?GHz and 12.87?GHz to 13.13?GHz, respectively.
