摘要： An antenna device includes a plate-shaped radiating element that radiates a radio wave polarized in an X-axis direction, a grounding electrode (GND), and a dielectric substrate that carries the radiating element and the grounding electrode (GND). In the dielectric substrate, dielectric in designated regions, which are included in adjustment regions that are located on the outer side with respect to first boundary planes and on the outer side with respect to second boundary planes, is thinner than dielectric in a non-adjustment region. The first boundary planes are planes extending on end faces of the radiating element on the respective sides in an X-axis direction (polarization direction) and being orthogonal to the X-axis direction. The second boundary planes are planes extending on end faces of the radiating element on the respective sides in a Y-axis direction and being orthogonal to the first boundary planes and to the Y-axis direction.

摘要： An antenna device includes a plurality of dipole antennas and a port. Each of the dipole antennas is connected to the port. The dipole antennas are arranged around the port. Each of the dipole antennas comprises two ends. The device further includes a plurality of passive elements. The ends of the dipole antennas and the passive elements are interchangeably arranged around the port such that each of the passive elements is situated between ends of two different antennas from the plurality of dipole antennas. One or more switches are configured to switch between an omnidirectional state, in which the ends of the dipole antennas are not connected to the plurality of passive elements, and a directional state, in which at least one end of one of the passive elements is connected to at least one end of one of the antennas.

摘要： An antenna assembly including an antenna reflector steering mechanism is disclosed. A reflector steering structure for adjusting the horizontal azimuth of a reflector includes a drive motor disposed on the rear surface of the reflector, a planet gear rotated by the drive motor, and a sectorial rack gear engaged with the planet gear and fixed to a support shaft, thereby achieving a compact design of an entire antenna structure. Further, by applying a structure with enhanced electrical insulation to rolling and slide contact portions of the drive unit and a portion undergoing change in contact pressure, radio performance of the antenna system may be prevented from changing according to steering of the reflector.

摘要： The invention relates to a directional antenna network adapted to operate in at least one predetermined frequency band, which comprises at least one pair of metal antennas (8,10) formed by a first metal antenna and a second metal antenna, the second metal antenna being sequentially rotated by a predetermined angle of rotation relative to the first metal antenna, a load circuit (6), with each metal antenna connected to said load circuit, and a monopole antenna (12), having a central position in the antenna network, connected to said load circuit (6). The metal antennas and the monopole antenna are arranged on a ground plane (4) and coupled, with the load circuit (6) being parameterized to provide radiation in which the monopole antenna (12) has a destructive contribution of a magnetic transverse radiation mode, whereby radiation by said at least one pair of metal antennas of selected circular polarization is obtained.

摘要： Example embodiments described herein relate to a modular telematics control unit (TCU) with directional Bluetooth Low Energy (BLE) and techniques for using the modular TCU with directional BLE. A modular TCU may include a housing configured to couple to a vehicle and a set of Bluetooth Low Energy (BLE) radios. Each BLE radio is coupled to a corresponding BLE antenna configured for omnidirectional operation. The set of BLE radios and BLE antennas are located within the housing. The modular TCU also includes a heat sink located within the housing and positioned proximate the BLE antennas such that the heat sink limits operation for each BLE antenna to a particular direction extending away from the housing. In some instances, a vehicle computing system may use BLE to detect a device and perform operations based on the location of the device relative to the vehicle.

摘要： A multiband antenna array includes a radiating element array having first and second rows of MIMO radiating elements. The two rows of MIMO radiating elements include a plurality of dual-polarised radiating elements. The radiating element array includes a dual-polarised low-band radiating element. A reflector array is provided, from which a) the dual-polarised radiating elements of the first and second rows of MIMO radiating elements and b) the dual-polarised low-band radiating element are spaced. The dual-polarised low-band radiating element includes at least four directive radiating element devices, which are each offset relative to one another by at least approximately 90° and delimit an accommodation space. In the accommodation space there are at least one or at least two dual-polarised radiating elements from the first row of MIMO radiating elements and at least one or at least two dual-polarised radiating elements from the second row of MIMO radiating elements.
