Abstract :
A polarisation-agile active patch antenna with a compact layout has been developed. Comprising a square patch with an overlay, it has two transistors in the common base configuration, connected on adjacent sides to excite orthogonal modes of oscillation. Circular polarisation of either sense, and linear polarisation parallel to either patch side or diagonal, can be radiated
