Abstract
AbstractThis paper proposes a novel orthogonally-polarized dual-band switchable microstrip antenna. The proposed antenna consists of a perpendicular feeding network and an radiator with a PIN-installed H-shaped slot. When the states of one single PIN diode in H-slot are controlled by bias voltages, the controlled physical geometry of the H-slot determines the operation frequencies of switchable 1.80 GHz and 2.43 GHz for vertically polarized linear polarization and fixed 2.06 GHz for horizontally linear polarization. The implemented antenna experimentally demonstrates reconfigurable dual-band capabi-lity by means of controling the states of the PIN diode. The simulation and measurement results of the implemented antenna have been in good agreement with the reflection coefficients, realized antenna gains and far-field radiation patterns at each of the PIN diode states.
