  • Methods and apparatus for beam steering using steerable beam antennas with switched parasitic elements
    Patent number: 8421684
    Abstract: An antenna is described. The antenna includes a planar circular structure. The antenna also includes a radiating element located at the center of the planar circular structure. The antenna further includes one or more parasitic elements located on a contour around the radiating element. The parasitic elements are aligned in parallel direction with the radiating element. The parasitic elements protrude from the planar circular structure. The antenna includes switches separating each of the one or more parasitic elements from ground. A switch in a first position creates a short between a parasitic element and ground. A switch in a second position creates an open circuit between the parasitic element and ground.
