, and equal‐phase feeding of the radiation waveguide is realised by changing the rotation direction. Compared with the multi‐level divider structure, the selected feed network can effectively reduce the size of the feeding network, especially in large array antennas [9]. A feeding network was designed and independently optimised at 94 GHz.…”

“…A SIW parallel-plate long-slot array dual circular polarisation low side-lobe level (SLL) antenna was presented [7]. However, in most radar systems at W-and Terahertz bands, all-metal antenna structure has been used with the properties of low loss, high power handing level, and good environmental adaptability [9][10][11][12][13]. A novel W-band monopole antenna is introduced in detail in Ref.…”

A W‐band dual‐beam low side‐lobe level antenna with a shared slotted waveguide radiating layer was designed by the authors. The proposed antenna consists of a symmetrical dual ports feed network layer located on two sides of the antenna, a novel shared symmetrical 4 × 32 slotted waveguide array radiation layer, and a bottom layer. The compact slot distance was adjusted to achieve deflection of the radiation pattern and reduce the radiation grating lobes. Good antenna radiation efficiency and port isolation were obtained by optimising the position of the slots at the radiation layer. A low side‐lobe level (SLL) was obtained using Taylor distribution was used in the design of the offset of each slot. The optimised antenna was fabricated and measured. Based on measurement results, the designed antenna has a 24.8 dBi far‐field gain, −17/–25.5 dB E/H plane side lobe level, and 19.8° beam deflection at 94 GHz. The performances of the two ports were in good agreement with each other, and the measured isolation was above 14.5 dB at 94 GHz.
