Abstract
A new microstrip antenna element is described which exhibits polarization agility. This is achieved by employing a T-slot radiator which is driven by the edge fields of a balanced microstrip line. The balanced line can support two propagating modes, namely, an even mode and an odd mode, and by switching between these modes, the orthogonal arms of the T-slot radiator are separately excited thus forming orthogonally polarized radiated fields. A microstrip patch antenna, which displays polarization agility using the same mechanism, is also described.
