A single-reflector design for omnidirectional coverage

Abstract

A single reflector antenna design is suggested for compliance with omnidirectional azimuth coverage requirements in radio base stations for point-to-multipoint services at millimetric bands. Free-space attenuation between the transmitter and receiver ends is accounted for by properly shaping the reflector profile to yield a cosecant-squared power pattern in the vertical plane. Numerical results highlight the comparison between the corresponding main coverage performance and that of usual dipole arrays. © 2000 John Wiley & Sons, Inc.
