Compact broad-band antenna with double linear polarisation

摘要

The antenna (2) has orthogonal dipoles (18), each comprising radiating elements (4), a reflector plane and an absorbing surface. The radiating elements are planar, where each element has triangular shape. The radiating elements are included in a same plane. Each radiating element has slightly rounded free edge (14). The dipoles are inscribed in a circle (K), where the free edge of each radiating element belongs to the circle. Each radiating element has top opposite to the free edge. The top of each radiating element is directed toward center (O) of the circle.
