Ellipticity reduction in circularly polarized array antennas is provided herein. An antenna array may include a processor that is configured to control a plurality of elements, each of the plurality of elements producing an elliptically polarized wave having an eccentricity value, the elliptically polarized wave traveling along a direction of propagation, wherein at least a portion of the plurality of elements are incrementally clocked around their direction of propagation, so that a combined output of the plurality of elements is substantially circularly polarized.

Ellipticity reduction in circularly polarized array antennas

Printed circuit board mounted antenna and waveguide interfaces are provided herein. An example device includes any of a dielectric substrate or transmission line, an antenna mounted onto the dielectric substrate, and an elongated waveguide mounted onto the dielectric substrate so as to enclose around a periphery of the antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide.

Printed circuit board mounted antenna and waveguide interface

Higher isolation solutions for printed circuit board mounted antenna and waveguide interfaces are provided herein. An example waveguide mounted onto a dielectric substrate can enclose around a periphery of an antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide. The waveguide can have a first portion having a first cross sectional area that is substantially polygonal that transitions to a second cross sectional area that is substantially conical. A shape of the radiation produced by the antenna is altered by the first portion as the radiation propagates through the first portion. A second portion includes an elongated tubular member coupled with the first portion.

Higher isolation solutions for printed circuit board mounted antenna and waveguide interfaces are provided herein. An example device includes any of a dielectric substrate or transmission line, an antenna mounted onto the dielectric substrate, and an elongated waveguide mounted onto the dielectric substrate so as to enclose around a periphery of the antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide, the elongated waveguide having a first cross sectional area and a second cross sectional area, and the first cross sectional area differs from the second cross sectional area.
