Title:
ANTENNA ARRAY HAVING A DIFFERENT BEAM-STEERING RESOLUTION IN ONE DIMENSION THAN IN ANOTHER DIMENSION
Document Type and Number:
WIPO Patent Application WO/2019/172955
Kind Code:
A3
Abstract:
In an embodiment, an antenna includes a one-dimensional array of antenna cells, a signal feed, and signal couplers. The antenna cells are each spaced from an adjacent antenna cell by less than one half a wavelength at which the antenna cells are configured to transmit and to receive, are configured to generate an array beam that is narrower in a dimension than in an orthogonal dimension, and are configured to steer the array beam in the dimension. And the signal couplers are each configured to couple a respective one of the antenna cells to the signal feed in response a respective control signal having an active level. For example, the antenna cells can be arranged such that a straight line intersects their geometric centers.
