摘要: We present here a novel architecture of high-gain continuous transverse stub (CTS) antenna array operating at E-band (71–86 GHz) with reduced sidelobe level (SLL). The consists an 16 long slots excited by nonuniform parallel-plate waveguide (PPW) corporate feed network. excitation is achieved the design asymmetrical power dividers in PPW technology, for which simple analytical models are provided. Full-wave simulations validated measurements prototype fabricated aluminum. SLL lower than −28 dB E-plane. Such 15 classical parallel-fed CTS arrays. overall remains below −18 over 75–86 GHz band. Its mean radiation efficiency 60%, and maximum 85% reached 86 GHz.
