Design of wideband low profile Ku band antenna array

Aperture coupled phased array antenna design at Ku band is introduced. The array spans entire Receive Band of Ku band (10.8 GHz – 12.75 GHz) and has a gain greater than 24.5 dBi with approximately 330×70×25 mm (LxWxH) dimensions. Low loss waveguide-microstrip type hybrid feed network is also designed and simulation results are presented. Aperture efficiency greater than 70% is achieved.
