摘要

The paper proposes a hexagonal planar antenna operating from 10.6695 to 40.1913 GHz covering X, Ku, K, and Ka bands. The hexagonal-shaped closed loop slot radiator is developed over an RT Duroid-5880 substrate with the dimension of 20 × 20 × 0.508 mm, using ANSOFT HFSS 15.0S. The results of simulations attain a bandwidth of return loss ≤ −10 dB which is 29.5218 GHz. VSWR is less than 2 means a stable antenna with an overall attainable maximum gain value of 34 dB and radiation directional patterns. Corner feeding technique is implemented to attain a massive bandwidth of 29.5218 GHz, and the defective ground structure system is implemented which certainly maintained positive gain at the resonances and caused a maximum gain of 34 db. The proposed system is suitable for satellite radar applications and the International Telecommunication Union’s (ITU) 5G band.
