Waveguide-based Meniscus Thin Lens for Broadband MM-wave Power Combining Applications
A meniscus thin lens integrated in a rectangular waveguide is presented for broadband high-efficiency power combining applications.The combiner structure is composed of ten side-by-side input waveguides,a meniscus thin lens with a matching layer,an E-plane sectoral horn,and an output waveguide.Simulation results from CST Microwave Studio show that the choice of the f/D number of the meniscus thin lens plays a significant role in achieving high combining efficiency and a matching layer also helps to improve the efficiency.For a ten-way combiner with center frequency of 30 GHz,a broad 80%-efficiency bandwidth of 11.5 GHz(28.5 GHz~40 GHz)has been achieved.
