- Abstract
- The invention relates to a Microwave radiation unit (10, 40) comprising a refractive beamformer (12) and at least one transmission line (14), where the at least one transmission line (14) is connected to the refractive beamformer (12, 42) by a transition structure (16, 50a, 50b, 50c, 50d, 50e), where the transition structure (16, 50a, 50b, 50c, 50d, 50e) comprises a coupling structure (18, 72) and a waveguide (20, 52a, 52b, 52c, 52d, 52e) having a main travel direction (T), where the refractive beamformer (12) and the waveguide (20, 52a, 52b, 52c, 52d, 52e) each comprise parallel metallic layers (C1-M1, C4-M2) and a solid dielectric body (36, 38) between the parallel metallic layers (C1-M1, C4-M2), where the solid dielectric body (36) of the waveguide (20, 52a, 52b, 52c, 52d, 52e) and the solid dielectric body (38) of the refractive beamformer (18) comprise at least one common connecting layer (L1, L2, L3, L4, C1-DL, C2-DL, C3-DL, C4-DL, P1, P2, P3) of one solid dielectric material (M1, M2, M3, M4) extending from the waveguide (20, 52a, 52b, 52c, 52d, 52e) into the refractive beamformer (18), so that the solid dielectric body (36) of the waveguide (20, 52a, 52b, 52c, 52d, 52e) and the solid dielectric body (38) of the refractive beamformer (12, 42) merge, at least partially, into each other. The invention is characterized in that the at least one common connecting layer (L1, L2, L3, L4, C1-DL, C2-DL, C3-DL, C4-DL, P1, P2, P3) extends over the whole lateral extension of the solid dielectric body (36) of the waveguide (20) and the solid dielectric body (38) of the beamformer (12).
