A circular dielectric polarizer can have a cylindrical shape and include a dielectric slab, a dielectric core, and at least one air cutouts portions of the dielectric core. The dielectric slab can include a first dielectric material and have a thickness centered about an axis of the cylindrical shape. The dielectric core can include a second dielectric material. Portions of the dielectric core can be located on different sides of the dielectric slab. The dielectric core and the dielectric slab can form the cylindrical shape. The dielectric constant of the first dielectric material can be higher than a dielectric constant of the second dielectric material. Parameters of the circular dielectric polarizer, the dielectric slab, the dielectric core, and the at least one air cutout are selected to obtain approximately a 90 degree difference in phase in a signal passing through the circular dielectric polarizer at a target frequency.

A method and apparatus for a polarizer. The apparatus comprises a dielectric rod, a first array of slots, and a second array of slots. The first array of slots and the second array of slots are formed in sidewalls of the dielectric rod. The first array of slots is substantially opposite to the second array of slots. The first array of slots and the second array of slots are configured to shift a first component orthogonal to a second component in a signal traveling through the dielectric rod by around 90 degrees with respect to each other. The dielectric rod may be a solid material or comprised of layers of dielectric substrates with metal tabs.

Waveguide polarizers

Antenna elements operable to radiate different patterns are provided. A particular apparatus includes a first antenna element having a plurality of radiating elements. Each of the radiating elements includes a first member having a first end and a second end. The first end is coupled to an antenna interface and the second end extends a length of the first member from the first end. Each of the radiating elements further includes a second member having a third end and a fourth end. The third end is electrically coupled to the first member at a point partway along the length of the first member. The fourth end extends away from the first member. When a first radiating element is radiating in the presence of a second radiating element, a null is generated in a radiation pattern of the first radiating element.

Wide scan phased array antenna element

A bandgap surface for use in a waveguide transition module. The surface may be constructed with a ground plane; a capacitive layer including a plurality of capacitive elements arranged in a polar configuration within a common plane, and spaced apart from said ground plane; and a plurality of electrically conductive vias formed within a dielectric layer of material that conductively couple said ground plane to each of said capacitive elements.

An antenna array core comprising a plurality of microwave modules, a control layer, a mounting layer, and a signal distribution layer. The control layer is capable of distributing control signals to the plurality of microwave modules. The plurality of microwave modules are attached to an upper surface of the mounting layer and the mounting layer is made from a heat conductive material capable of cooling the plurality of microwave modules. The signal distribution layer is located below the mounting layer, wherein the signal distribution layer is capable of transmitting microwave signals to the plurality of microwave modules and wherein the arrangement of the plurality of microwave modules on the mounting layer, the control layer, and the wave distribution network form a layered architecture for the antenna core. The architecture is a balance between, size, thermal control, manufacturability, cost, and performance so as to be a unique solution.

Phased array antenna architecture

A method and structure for producing an angled RF connection between a first element and a second element using a flexible substrate is provided. The method includes laminating a flexible substrate onto the first element; bending the flexible substrate such that a bonding pad on the flexible substrate is in a similar plane as a bonding pad on the second element; and creating the angled RF connection by wire bonding the bonding pad on the flexible substrate and the bonding pad on the second element. The structure includes a flexible substrate that is laminated onto a first element as an outer layer, flexible substrate having at least one bonding pad, and the flexible substrate able to bend in an angle that places the bonding pad in a same plane as a bonding pad on a second element.

Method and system for angled RF connection using a flexible substrate

Various techniques are disclosed to suppress undesired signal components introduced by non-linear amplifiers of phased array antenna systems to accommodate bandwidths greater than one octave. For example, in accordance with one embodiment, a phased array antenna system includes first and second antenna elements adapted to provide first and second received signals in response to a radio signal. The second antenna element is rotated approximately 180 degrees in relation to the first antenna element. Amplifiers may amplify the received signals to provide amplified signals having a bandwidth greater than one octave. Undesired components of the amplified signals introduced by the amplifiers may be suppressed through appropriate phase shifts performed by associated phase shifters and/or power combiners. A power combiner may combine the first and second output signals to provide a combined signal, wherein the first and second undesired components are suppressed in the combined signal relative to the amplified signals.
