Antenna reflector broadband a flat wire antenna with circular polarization and method of making the reflector antenna

摘要

Antenna reflector on which can be mounted flat wire antenna with circular polarization (2) which can emit electromagnetic radiation in two directions orthogonal to the plane of the antenna (2) in a predetermined frequency band, characterized the antenna reflector ( 3) comprising: - at least one reflection zone (341A) of a first type, each of said regions of a first type adapted to reflect, with a displacement of next phase 180 degrees, an electric field radiation electromagnetic rear called whose frequency is included in a first subband of the frequency band, each of said reflecting zones (341A) of a first type adapted to be facing a zone of the antenna (2) which can emit radiation electromagnetic in the first subband of frequencies corresponding to a distance that allows the electric field of electromagnetic radiation rear r eflejada is substantially in phase with the electric field of electromagnetic radiation called front; and - at least one reflection zone (342A, 343A) of a second type, each of said regions of a second type adapted to reflect, with an offset comprised phase between two angle values ​​around the value zero, the electric field of the back electromagnetic radiation whose frequency is within a second subband of the frequency band, each of said reflection areas (342A, 343A) of a second type adapted to be opposite to an area of ​​the antenna ( 2) which can emit electromagnetic radiation at the second frequency subband corresponding to a distance that allows the electric field of the reflected electromagnetic radiation back is substantially in phase with the electric field of the electromagnetic radiation front.
