摘要:
An integrated radar system includes a processing module and a radar device. The radar device includes an antenna module, a configurable shaping module, and a configurable transceiver module. The processing module generates an outbound signal and a control signal to configure the integrated radar system. The configured transceiver module converts the outbound signal into an outbound wireless signal. The configured shaping module shapes the outbound wireless signal into a shaped signal. The antenna module transmits the shaped signal and then receives an inbound radar signal. The configured shaping module shapes the inbound radar signal into an inbound wireless signal. The configured transceiver module converts the inbound wireless signal into an inbound symbol stream. The processing module determines location information regarding an object based on the inbound symbol stream.

A tunable projected artificial magnetic minor (PAMM) includes a plurality of artificial magnetic minor (AMM) cells and a control module. The AMM cells collectively produce an artificial magnetic conductor (AMC) having a geometric shape a distance from a surface of the tunable PAMM for an electromagnetic signal in a given frequency range. The control module is operably coupled to the plurality of AMM cells and provides control information to one or more of the AMM cells to tune at least one of the geometric shape of the AMC and the distance of the AMC from the surface of the tunable PAMM.

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; determine angular position of a source of the inbound wireless signal 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.

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.

A programmable antenna includes a substrate, metallic inclusions, bidirectional coupling circuits, and a control module. The metallic inclusions are embedded within a region of the substrate. The bidirectional coupling circuits are physically distributed within the region and are physically proximal to the metallic inclusions. The control module activates a set of bidirectional coupling circuits, which, when active, the set of interconnects a set of metallic inclusions to provide a conductive area within the region. The conductive area functions an antenna.

A system includes a support device and an elongated spiral antenna coupled to the support device. The elongated spiral antenna has a contracted portion and an expanded portion. The expanded portion provides beam steering and directivity. The system also includes a feed line coupled to the elongated spiral antenna. A method for forming the elongated spiral antenna uses a predetermined formula to form arms of the elongated spiral antenna. The arms can be formed by printing the arms on a printed circuit board.
