Summary:
A millimeter-wave cylindrical conformal array with 120° flat-top broad beam and a stable 30° downward tilted-angle is demonstrated, fabricated and measured in this paper. A 32-element longitudinal slots array antenna is selected as the radiating element of the cylindrical conformal array, which is wrapped around the cylindrical in the circumferential direction. A 1-to-8 unequal power divider and a compact phase compensating network are developed as the feed network for the designed ×slot array. Measured results show that a 120° flat-top broad beam with stable 30° downward angle is achieved over the operating frequency band. The proposed new conformal array antenna can be used in millimeter wave base station system.
