Antenna array

Abstract

Abstract A planar array antenna in strip-line technology is proposed which is especially suitable for the reception of X-Band satellite broadcast signals. The mechanical construction consists of a first substrate plate (10) as a carrier for antenna elements (11) and a second substrate plate (18) as a carrier for the coupler and the signal processing. The two substrate plates are connected to one another by a metal plate (13) whose thickness (d) corresponds to half the operating wavelength. The electrical connection between the antenna elements on the front side of the antenna and the couplers on the rear side of the antenna is produced by coaxial conductor pieces which are fed in an insulated manner through holes (14) in the metal plate. In a further variation of the array antenna according to the invention, with three substrate plates and two metal plates, it is also possible to receive circular-polarised signals. <IMAGE>
