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 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 illustrate the trade-offs involved when considering certain antenna design aspects as well as feed requirements. The role of both Geometrical and Physical Optics is carefully explored along design and analysis steps with a view towards guiding the reader through key factors of this study in an appropriate sequence. The importance of proper modelling of feed patterns is also evidenced
