Polarization diversity antenna |
摘要 |
A crossed-dipole antenna having four antenna elements, the polarization of which is easily changed from vertical linear polarization to horizontal linear polarization. A switching network coupled to the crossed-dipole antenna includes pin diodes operating as radio frequency switching elements which provide a means for electronically switching the polarization of the crossed-dipole antenna. A positive biased voltage applied to the switching network results in the crossed-dipole antenna being polarized linearly in a horizontal direction. A negative biased voltage applied to the switching network results in the crossed-dipole antenna being polarized linearly in a vertical direction.
