The waveguide assembly includes a plurality of radiating element probes for coupling to respective radiating elements of the antenna array, and a plurality of phase-mode feed probes. A variable phase shifter is positioned in the waveguide assembly in an annular region between the radiating element probes and the phase-mode feed probes to cause additional progressive electrical phase shifts of the radiating elements of the antenna array from 0 to 2πK radians, the phase shift progressing for one complete physical angular cycle in the plane of the waveguide assembly. A beam forming network couples the phase-mode feed probes to a plurality of phase-mode feed ports corresponding to respective consecutive-order phase modes of the antenna array. When coupled to the antenna array, respective orders of the phase modes provided at the phase-mode feed ports are selectable in accordance with K. | 2018-04-19 |

20180108993 | ELECTRONIC DEVICE INCLUDING RADIATING MEMBER - An electronic device includes a housing at least partially comprising a metal-material portion, a slit formed in the housing to traverse the metal-material portion along a first direction, and a radiating member, at least a portion is positioned on the slit. The radiating member includes a substrate, a first loop coil pattern formed on a first surface of the substrate, a second loop coil pattern formed on a second surface of the substrate that is opposite the first surface, a connection pattern formed on the first surface of the substrate and connected to each of the first loop coil pattern and the second loop coil pattern, and a bridge pattern formed on the second surface of the substrate and extending in a second direction intersecting the first direction. The bridge pattern bypasses the connection pattern, and is combined with the first loop coil pattern to form a loop coil antenna. | 2018-04-19 |
