V-band dipole phased array antennas on extended hemispherical dielectric lenses

A novel V-band 1 × 4 dipole phased array antenna on extended Hemi-spherical dielectric lenses using a microstrip Rotman lens is presented. This phased array antenna employs an integrated lens as a reflector to tilt the main beam in broadside direction. A prototype phased array system is designed with 7 beam ports, 4 array ports, and 8 dummy ports. A 60 GHz four element dipole linear array antenna is proposed with a nonplanar structure to scan over(−40°, +40°).
