Abstract
Antennas with reconfigurable periodic structures are provided. The antenna includes a ground plane, a periodic structure comprising a plurality of conductive patches, and an antenna structure on the periodic structure. Ones of the plurality of conductive patches are selectively electrically connected to adjacent ones, to the ground or not connected to the ground. The antenna structure is configured to resonate at a resonant frequency of the antenna.
Claims18
An antenna, comprising:
- a ground plane in a first layer of a printed circuit board;
- a periodic structure comprising a plurality of conductive patches in a second layer of the printed circuit board;
- and
- an antenna structure in a third layer of the printed circuit board that is on the second layer of the printed circuit board comprising the periodic structure,
- wherein ones of the plurality of conductive patches are selectively electrically connected to adjacent ones of the plurality of conductive patches or to the ground plane,
- wherein the antenna structure is configured to resonate at a resonant frequency of the antenna, and
- wherein a direction of a radiation pattern of the antenna is determined based on selectively electrically connecting ones of the plurality of conductive patches to the ground plane or to the adjacent ones of the plurality of conductive patches in the second layer of the printed circuit board.
