Abstract: The disclosed structures and methods are directed to antenna systems configured to transmit and receive a wireless signal in and from different directions. A switchable lens antenna has excitation ports radiating radio-frequency (RF) wave into a parallel-plate waveguide structure, and a frequency selective structure (FSS). The antenna presented herein is configured to operate in two modes depending on an initial steering angle of the RF wave propagating in the parallel-plate waveguide structure. When the initial steering angle is about or less than a threshold steering angle, FSS is OFF due to its stubs being electrically disconnected from the parallel-plate waveguide structure. When the initial steering angle is higher than the threshold, FSS is ON with stubs being electrically connected to the parallel-plate waveguide structure. When ON, FSS provides phase variance to the RF wave propagating in the parallel-plate waveguide structure and increases steering angle of the RF wave.

Abstract: The disclosed systems, structures, and methods are directed to antennas for integration with a display structure which has a plurality of pixels arranged in pixel rows with an inter-pixel spacing, and a feeding line located in the inter-pixel spacing. The display structure also has an antenna which comprises a slotted waveguide and a substrate. The slotted waveguide is located in the inter-pixel spacing and defines a plurality of slots configured to radiate electromagnetic waves. The substrate is attached to the slotted waveguide and is located between the feeding line and the slotted waveguide. The antenna may also include a plurality of slotted waveguides superposing on different feeding lines of the display structure.
