A wideband compact antenna of very small thickness and with dual orthogonal linear polarization, operating in the v/uhf bands

摘要

An antenna (2) for emitting/receiving electromagnetic waves of the type comprising two dipoles (16A, 16B) orthogonal to each other, each dipole (16A, 16B) comprising two radiating elements (4), a metal plate (8), and an absorptive structure (6). The radiation elements (4) are all substantially planar, both dipoles (16A, 16B) being substantially comprised in a same plane (P), and the absorptive structure (6) is interposed between the metal plate (8) and the dipoles (16A, 16B) and is laid out in contact with the metal plate (8).
