Abstract
An extremely-low-profile helical array antenna has been designed for a frequency band of 11.7 GHz to 12.0 GHz. Calculations show how proper spacing of the helical elements serves to reduce the deterioration in the directivity of a helical array antenna when the radiation beam is tilted from the normal direction of the array plane. The measured aperture efficiency shows a maximum value of 80% for a beam radiated in the normal direction and 71% for a 30 degrees beam tilt.<>Keywords
