Array of shielded elements as in Figure 2. Gain on the principal elevation plane 𝜙=0° of a 140×140 array at 5 GHz. All the ports are fed, exciting a circularly polarized field (its 𝜃 component in solid black line, its 𝜑 component in dashed gray line). (a) Beam pointing at broadside (𝜃=0°). (b) Beam pointing at 𝜃=30°.
