Design and Development of Low-Cost Low Sidelobe Level Slotted Waveguide Antenna Array in X-Band

摘要

This paper presents a low-cost low-profile compact waveguide-fed slotted antenna array with very low average sidelobe level (ASLL) in X-band. The desired current distribution on the antenna array’s aperture is synthesized using technique combined with technique. The antenna array design based on the synthesized current distribution is carried out using -based commercial simulator. The designed antenna is fabricated using a low-cost fabrication process. The measured results obtained are in good agreement with the simulated results. This work is extremely useful for the radar applications.
