摘要： An RFID tag is described with an antenna and a passive reflector. In an example, the RFID tag has a dielectric substrate. A first conductive pattern is on the dielectric substrate to form an antenna. An RFID integrated circuit (IC) chip is on the dielectric substrate having an antenna port electrically coupled to the antenna, the antenna port being configured to provide RF energy from a reader to the RFID IC chip through the antenna, the RFID IC chip being configured to provide a response to the reader through the antenna. A second conductive pattern is on the dielectric substrate beside the antenna in the form of a second dipole to form a passive reflector that is not electrically coupled to the antenna port, the passive reflectors being configured to reflect RF energy from the reader away from the antenna.

摘要： An offset imaging antenna system with compensated optical aberrations comprises a main a paraboloid reflector, a first paraboloid sub reflector, and a first feeding array as an arrangement of first feed array elements to illuminate or to be illuminated by the first sub reflector. The main reflector and the first sub reflector are confocal by sharing a common focal point. The first feeding array has a curved shape that corresponds to a first equivalent array of magnified image feed elements lying on a plane crossing the main optical centre and perpendicular to the main bore-sight axis, all the first feed array elements being positioned as to provide a planar distribution of the positions of the image feed elements onto the first equivalent array after a second reflection by the main reflector with a central image point coinciding with the main reflector optical centre under a maximum illumination condition.

摘要： An antenna includes a first radiating element configured to emit first electromagnetic radiation in response to at least one feed signal having a frequency within a first radio frequency (RF) band. A director is provided, which is positioned forwardly of the first radiating element, and in a path of the first electromagnetic radiation. The director includes first and second passive impedance elements that provide respective first and second frequency-dependent reactances to first currents induced within the director in response to the first electromagnetic radiation. The first and second passive impedance elements may include a first inductor and a first capacitor, which are electrically coupled in series. The director may also be configured to include a plurality of passive impedance elements that are connected within an impedance loop containing a second LC circuit in series with a first LC circuit.

摘要： An electronically steerable antenna includes at least one driven element, at least one controllable counterpoise element, and a support structure on which the driven element and the controllable counterpoise element are disposed. The controllable counterpoise element has at least one geometric characteristic which can be varied. A radiating angle of the driven element is selectively controlled, at least in part, by modifying the geometric characteristic of the at least one controllable counterpoise element. The counterpoise element may include multiple conductive segments, at least a subset of which may be adapted to be individually electrically connected together so as to modify the radiating angle of the driven, element.

摘要： The invention relates to an antenna array for a radar transceiver, especially for distance and/or speed detection in the surroundings of motor vehicles. Said antenna array comprises at least one first part (110; 112; 114, 115), arranged on a chip (101), and a second part (210) which is arranged at a distance to the first part (110; 112; 114, 115) and which is indirectly fed by the first part (110; 112; 114, 115). The inventive array is characterized in that the second part (210) of the antenna is mounted on an antenna support (400) or an additional chip (420) which is mounted above the first part (110; 112; 114, 115) by means of flip-chip connections (300).

摘要： A built-in antenna device that broadens bandwidth and that realizes further miniaturization and thin-modeling without making a device itself a flat shape, while still enhancing gain and reducing SAR (specific Absorption Rate). The self impedance of dipole antenna 12, the self impedance of parasitic element 14, and the mutual impedance between dipole antenna 12 and parasitic element 14 change as the length and girth of dipole antenna 12 and parasitic element 14, and the distance therebetween are adjusted to predetermined levels, so as to broaden bandwidth by changing the input impedance of built-in antenna 10.
