Abstract (en)
[origin: EP0071069A2] In a microwave antenna (1), consisting of a waveguide emitter and two exciter emitters (14), controlled by a hybrid (12) and arranged at 90 DEG with respect to each other perpendicular to the axis of the waveguide emitter, for right-hand and left-hand circularly polarised electromagnetic waves, in order to achieve a high-precision phase difference of the polarisation components with simple, cost-saving means, which are as suitable as possible for quantity production, the exciter emitters (14), the hybrid (12) and their connecting lines (13) are designed on a substrate (7) in printed technology, the part of the substrate (7) carrying the exciter emitters (14) being arranged transversely in the waveguide emitter. <IMAGE>
