Abstract
A novel design of a polarization-agile microstrip-line-coupled-fed patch antenna is proposed. The simple structure of the proposed antenna consists of a square patch symmetrically loaded with two PIN -diode connected short-circuited stubs, and the use of proximity-coupled feed allows inherent impedance matching and RF and DC signal isolation without the need of DC blocking components. The fabricated 1.6-GHz prototype of our proposed antenna, when biased with different DC voltages, can achieve linear and right- and left-handed circular polarizations, respectively.
