Abstract: A three-dimensional multiple spiral antenna includes a substrate, a plurality of spiral antenna sections, and a feed point module. The substrate has a three-dimensional shaped region and each spiral antenna section is supported by a corresponding section of the three-dimensional shaped region and conforms to the corresponding section of the three-dimensional shaped region such that, collectively, the spiral antenna sections have an overall shape approximating a three-dimensional shape. The feed point module is coupled to a connection point of at least one of the spiral antenna sections.

Abstract: An antenna assembly a spiral antenna feed and a programmable circuit. The spiral antenna feed includes a substrate, a spiral antenna element, and a feed point. The substrate has a three-dimensional hyperbolic shaped region, which supports the spiral antenna element such that the spiral antenna element has an overall shape approximating a three-dimensional hyperbolic shape. The feed point is coupled to a connection point of the spiral antenna element. The programmable circuit produces a projected artificial magnetic conductor reflector dish that reflects an inbound RF signal to the spiral antenna feed and reflects an outbound RF signal from the spiral antenna feed.

Abstract: An antenna circuit includes a substrate, an antenna, and a projected artificial magnetic mirror (PAMM). The antenna is fabricated on the substrate and is positioned in a region of the substrate that has a high permittivity. The PAMM produces an artificial magnetic conductor at a distance above a surface of the substrate to facilitate a radiation pattern for the antenna.

Abstract: An antenna system includes an antenna structure and an antenna interface. The antenna structure includes ‘x’ number of spiral antenna sections. Each spiral antenna section transmits a different phase of ‘x’ phases of an outbound RF signal and receives a different phase of ‘x’ phases of an inbound RF signal. The antenna interface generates the ‘x’ phases of the outbound RF signal by splitting the outbound RF signal into ‘x’ copies and phase shifting each of the ‘x’ copies. The antenna interface also combines the ‘x’ phases of the inbound RF signal to produce the inbound RF signal by phase shifting each of the ‘x’ phases of the inbound RF signal by the respective phase shift and combining the ‘x’ copies.

Abstract: An antenna assembly includes a substrate, a plurality of spiral dipole antenna sections, and a phase array feeder. The substrate has a three-dimensional shaped region. Each of the spiral dipole antenna sections is supported by a corresponding section of the three-dimensional shaped region and conforms to the corresponding section of the three-dimensional shaped region such that, collectively, the plurality of spiral dipole antenna sections has an overall shape approximating a three-dimensional shape. The spiral dipole antenna sections are coupled together in accordance with a coupling configuration for beamforming and/or power combining. The phase array feeder inputs, or outputs, a phase offset representations of a radio frequency (RF) signal from, or to, the spiral dipole antenna sections and converts between the phase offset representations of the RF signal and the RF signal.

Abstract: A receiver includes an antenna array, an angular positioning module, a low noise amplifier module, and a down conversion module. The antenna array is operable to receive an inbound wireless signal. The angular positioning module is operable to: receive a plurality of received inbound wireless signals from the antenna array. An angular position of a source of the inbound wireless signal is determined from at least some of the plurality of received inbound wireless signals based on a first radiation pattern and a second radiation pattern of the plurality of received inbound wireless signals; and output a representation of the inbound wireless signal. The low noise amplifier module is operably coupled to amplify the representation of the inbound wireless signal to produce an amplified inbound wireless signal. The down conversion module is operably coupled to convert the amplified inbound wireless signal into a baseband or near baseband signal.
