Abstract: An apparatus, system, and method are disclosed for phased array antenna communications. A phased array antenna tile includes a plurality of antenna elements. A beamformer module is integrated into the phased array antenna tile. The beamformer module is electrically coupled to each antenna element to process directional signals for the plurality of antenna elements. A plurality of cascadable connection points are disposed along a perimeter of the phased array antenna tile for connecting the phased array antenna tile to one or more additional phased array antenna tiles.
Abstract: An antenna, multi-band antenna system, and antenna apparatus for radio frequency communications are disclosed. The antenna includes a first antenna core, a multi-band antenna array located on the first antenna core, a second antenna core laminated to the first antenna core, an antenna ground plane located on the second core, and a plurality of feed networks interspersed on the first antenna core and the second antenna core. The first antenna core and the second antenna core form dielectric columns between the multi-band antenna array and the antenna ground plane. The antenna may also include a low noise block feed connection located on the first antenna core.
Abstract: An apparatus and system are disclosed for a double gimbal stabilization platform. The apparatus, in one embodiment, includes a base and a first pivot joint connected to the base. The apparatus also includes a bent gimbal structure connected to the first pivot joint. The first pivot joint may rotate the bent gimbal structure about a first axis of rotation. The apparatus includes a second pivot joint connected to the bent gimbal structure. The apparatus includes a platform connected to the second pivot joint. The second pivot joint may rotate the platform around a second axis of rotation and the second axis of rotation may be orthogonal to the first axis of rotation. Furthermore, a center of mass for a combination of the bent gimbal structure and the platform may be between the base and the first axis of rotation.

Abstract: An apparatus, system, and method are disclosed for phase shifting and amplitude control. A two-phase local oscillator generates an in-phase sinusoidal signal of a fixed frequency and a quadrature sinusoidal signal of the fixed frequency having a ninety degree phase shift from the in-phase sinusoidal signal. A signal generator receives the in-phase sinusoidal signal and the quadrature sinusoidal signal and generates a controllable sinusoidal signal of the fixed frequency. The controllable sinusoidal signal has a variable amplitude and a shiftable phase. A mixer varies the amplitude and shifts the phase of an input signal by mixing the input signal with the controllable sinusoidal signal to generate an output signal. The input signal and the output signal carry phase and amplitude information required for phased array signal processing. Either a receiver or a transmitter may be implemented using the present invention.
