Limitations And Advantages Of A Directional Antenna Fixed beam antenna has fixed gain profile with a primary lobe pointing in a single direction. We only can steering the beam by changing the orientation of the antenna physically , which permit relatively slow changes at best. This kind of antenna does provide high gain for their cost and are widely deployed in practice.
