摘要
The invention is applicable to the field of circular-polarized planar wire antennas for very wide band telecommunications systems. It relates to an antenna reflector (3) for such an antenna (2), an antenna device comprising the antenna reflector (3) and the antenna (2), and a method for implementing the antenna reflector (3). The antenna reflector (3) according to the invention is based on a hybrid structure comprising, on the one hand, a first reflection region (341A) exhibiting electromagnetic properties of an electrical conductor in a first subband of frequencies and, on the other hand, a second reflection region (342A) exhibiting electromagnetic properties akin to a magnetic conductor in a second sub-band of frequencies. Each reflection region (341A, 342A) is designed to face a region of the antenna able to emit electromagnetic radiation in the corresponding sub-band of frequencies in order to reflect the electric field of the backward radiation in phase with the electric field of the forward radiation.
