Abstract
A reconfigurable antenna array including a plurality of identical elementary unit cells, each unit cell having at least one symmetry and being a square unit cell, and including a radiating element having at least four ports distributed in pairs on either side of each median on one side of a unit cell, the antenna array additionally including a reconfigurable switching circuit configured to generate three distinct connection states between each port of each pair of facing ports, each port of a pair belonging to two distinct elementary unit cells that are vertically stacked or horizontally adjacent within the antenna array.
Claims12
A reconfigurable antenna array, comprising:
- a plurality of identical elementary unit cells, each elementary unit cell having at least one symmetry and being a square cell, and comprising a radiating element having at least four ports distributed in pairs of facing ports on either side of each median on one side of the elementary unit cell,
- wherein the antenna array further comprises a reconfigurable switching circuit configured to impose a specific excitation mode on each of the ports while being configured to generate three distinct connection states between each port of each pair of the facing ports, each port of a given pair of facing ports belonging to two distinct elementary unit cells of the plurality of elementary unit cells, superimposed vertically or adjacent horizontally, within said antenna array.
