Abstract: The disclosed structures and methods are directed to antenna systems configured to transmit and receive a wireless signal in and from different directions. An antenna structure comprises a pair of horizontal-polarization (HP) antenna units forming a first parallel-plate waveguide. One of the HP antenna units and a base unit form a second parallel-plate waveguide. The antenna further comprises a pair of vertical-polarization (VP) antenna units each located in one of the first and second parallel-plate waveguides. Each HP antenna unit comprises inverted F antennas (IFAs) configured to radiate a radio-frequency (RF) waves that are horizontally polarized. Each VP antenna unit comprises VP excitation elements configured to radiate the RF waves that are vertically polarized. A method for manufacturing of the antenna structure is also disclosed.

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 structures and methods are directed to transmission and reception of a radio-frequency (RF) wave. An antenna comprises a stack-up structure having a first control layer, a second control layer, a first and a second parallel-plate waveguides, and a plurality of through vias. The antenna further comprises a first central port and a second central port being configured to radiate RF wave into the two parallel-plate waveguides independently; vertical-polarization peripheral radiating elements integrated with the first control layer and configured to radiate RF wave in vertical polarization; and horizontal-polarization peripheral radiating elements integrated with the second control layer and configured to radiate RF wave in horizontal polarization. A central port for transmission of RF wave into the stack-up structure of the antenna is also provided. Each vertical-polarization peripheral radiating element is collocated with one of the horizontal-polarization peripheral radiating element such that they cross each other, and that a RF wave radiation beam may be steered at an angle of 0 to 360 degrees in the plane of the stack-up structure, around the central port
