A corporate feed waveguide slot array antenna with broad bandwidth characteristics is designed for the 38-GHz (Ka-band) and 73.5-GHz (E-band) in order to increase the operating frequency band and the gain at the satellite communication frequency. The proposed antennas use multi layer feeding structure for stable fabrication process. For Ka-band frequency, a 8×8-element array antenna shows 27.7 dBi antenna gain with over 80% antenna efficiency and more than 3.923 GHz or 10.27% for 8×8-elements (36.254-40.177 GHz), a 16×16-element array antenna shows 33.8 dBi antenna gain with over 80% antenna efficiency and more than 3.867 GHz or 10.16% for 16×16-elements (36.133-40GHz), and 32×32-element array shows 39.8 dBi antenna gain with over 70% antenna efficiency and more than 3.583 GHz or 9.43% for 32×32-elements (36.19-39.773GHz), respectively. For E-band frequency, an 8×8-element array antenna shows 27.8 dBi antenna gain with over 80% antenna efficiency and 7.016GHz or 9.56% bandwidth (69.9-76.9GHz), while 16×16-element array antenna shows 33.8 dBi antenna gain with over 80% antenna efficiency and more than 7.042 GHz or 9.6% bandwidth (69.85-76.9GHz), and 32×32-element array shows 39.9 dBi antenna gain with over 70% antenna efficiency and more than 6.926GHz or 9.48% bandwidth (69.63-76.55GHz), respectively.
