MINIATURIZED ANTENNA FOR CONVERTING AN ALTERNATIVE VOLTAGE TO A MICROWAVE AND VICE-VERSA, IN PARTICULAR FOR WATCHED APPLICATIONS

摘要

The invention relates to a linear or circular polarization antenna, comprising a dielectric substrate and a conductive element fixed on the dielectric substrate and being delimited at its periphery by an edge which confers on this element a double planar symmetry along two perpendicular axes. In one embodiment, said conductive element has an excitation point on a first axis and a first pair of slots extending on the second of said axes from the periphery to the second axis. center of said conductive element. BR/ In another embodiment, said conductive element comprising an excitation point being on a third axis bisecting the angle formed between the first and second axes and respectively on two pairs of slots which extend respectively on the first and second of said axes, from the periphery to the center of said conductive element. / P
