40GHz band 4-element patch array antenna

Fabrication of a 40GHz band 4-elements patch array antenna. Planar antenna elements have been printed on an aluminum ceramic substrate of 0.1 mm thickness only. In order to cut down dielectrical losses as low as possible and positive influence bandwidth and radiating efficiency, the substrate was mounted above an air filled cavity. This printed antenna has an inter-element separation of 3.75mm and 2.9mm-female coaxial connectors. The antenna impedance matching has been tuned at 42.7GHz with a 3GHz bandwidth at 10dB return loss limit.

This antenna has application in many fields and the design expertise gained in OBANET and the measured results will be a solid base to continue working in the design of similar antennas to be used in laboratory environment. Know-how and test equipment at 40 at 60GHz is available for future R&D activities.
