Abstract
A system may include a meta-surface including multiple unit cells arranged along the meta-surface. Structural parameters of each unit cell may vary along the meta-surface. The system may further include at least a first active feed unit directed toward the meta-surface to generate a first beam. The first active feed unit may be configured to move relative to the meta-surface parallel to a 2-dimensional plane. The first beam is steerable by moving the first active feed unit.
Claims20
A system comprising:
- a meta-surface including multiple unit cells arranged along the meta-surface, wherein each unit cell includes a resonating structure, and wherein structural parameters of each unit cell vary along the meta-surface;
- and
- a first active feed unit directed toward the meta-surface to generate a first beam, wherein the first active feed unit is configured to move relative to the multiple unit cells arranged along the meta-surface parallel to a 2-dimensional plane, and wherein the first beam is steerable by moving the first active feed unit.
A device comprising:
- a transmit array panel including multiple unit cells arranged along a surface, wherein each unit cell includes a resonating structure, and wherein structural parameters of each unit cell vary along the surface, wherein each unit cell comprises:
- a first circular patch positioned on a first dielectric substrate;
- a first square patch positioned on a second dielectric substrate;
- a second square patch positioned on a first side of a third dielectric substrate;
- and
- a second circular patch positioned on a second side of the third dielectric substrate, wherein the resonating structure includes the first circular patch, the first square patch, the second circular patch, and the second square patch.
