摘要： An angle-of-arrival antenna system uses two orthogonal arrays of patch antenna elements to measure the angle of arrival of a wireless signal irrespective of its polarization. Each antenna element has an antenna patch located over a corresponding ground patch. A shorting wall directly electrically connects one edge of the antenna patch to a corresponding edge of the underlying ground patch. The edge of the ground patch is also directly connected to a system ground plane. No other edges of the ground patch are connected to the system ground plane. The shorting wall acts as an impedance that isolates the ground patch from the system ground plane, and therefore improves isolation between the antenna elements. The antenna system may be constructed using conventional circuit-board fabrication techniques by implementing each shorting wall as an array of plated through-holes or slots.

The system comprises a high-precision GNSS antenna and a MIMO 5G multi-element antenna system. All the antennas within the proposed compact system are integrated with a shielded housing that enables electronic components of GNSS receiver and 5G modem to be arranged inside. The proposed integrated system has the following advantages: 1) compactness, 2) high efficiency of MIMO 5G antenna system, 3) a high degree of decoupling between 5G antennas, 4) a high degree of decoupling between 5G and GNSS antennas.

摘要： An antenna module is disposed to an electronic device includes a fixed member, a rotating component, a reflector, a director, and an antenna unit. The electronic device includes a first body and a second body. The first body has a first surface and a second surface. The fixed member is disposed to the first body fixedly. The rotating component is connected to the fixed member rotatably. The reflector and the director are disposed to the rotating component. The antenna unit is disposed to the first body and between the reflector and the director. When the first body and the second body rotate relative to each other, the reflector is located between the antenna unit and one of the first surface and the second surface, and the director is located between the antenna unit and another one of the first surface and the second surface.

摘要： A guest engagement system and associated methods provide seamless engagement with guests of facilities through the use of wireless sensing technologies. The system makes use of individual guest devices which are carried by guests and used to automatically identify and authenticate the guests throughout the facility. Services can thereby be seamlessly provided to the guests throughout the facility. The services include contact tracing, automatic unlocking of doors, including hotel or state room doors, based on the guests' immediate proximity to their assigned room's door. The services also include automated payment services provided at checkout or vending terminals, and automated log-on to interactive displays and portals, among others, based on secure wireless authentication of the guest devices.

摘要： An antenna unit includes a feed point, a first antenna conductor extending from the feed point and having a width that expands as a distance from the feed point increases, a second antenna conductor facing a top end edge of the first antenna conductor with a gap formed therebetween, a first connection part connecting the top end edge of the first antenna conductor and the second antenna conductor via a capacitor, and a second connection part connecting the top end edge of the first antenna conductor and the second antenna conductor via an inductor or a zero-ohm resistor. A first connection point between the first connection part and the first antenna conductor is closer to a center of the top end edge of the first antenna conductor compared with a second connection point between the second connection part and the first antenna conductor.

摘要： An antenna for electrical coupling to a wireless communication circuit includes a first conductive strip segment having a first length, a second conductive strip segment having a second length different from the first length and coupled to the first conductive strip segment at a feed point to be electrically coupled to the drive node, and a third conductive strip segment having a third length less than both the first length and the second length. A first end of the third conductive strip is coupled to the feed point and a second end is coupled to circuit ground. The first conductive strip segment provides a first specified operating frequency range at a fundamental resonance mode corresponding to the first length plus the third length, and the second conductive strip segment provides a second specified operating frequency range at a fundamental resonance mode corresponding to the second length plus the third length.
