    摘要: The present disclosure provides an antenna device and a manufacturing method therefor, a control method, and an electronic device. The antenna device includes a first and a second substrate structure, and a liquid crystal layer between the first and the second substrate structure. The first substrate structure includes a first substrate and multiple antenna patches. The second substrate structure is on the side of the multiple antenna patches away from the first substrate, and includes a second substrate and a metal layer having multiple gaps. One gap corresponds to one antenna patch, the region where the orthographic projection of each gap on the first substrate overlaps that of the corresponding antenna patch is a first region, the orthographic projection of each gap on the first substrate further includes a second region and a third region, and the third region is located between the second region and the third region.

    摘要: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than a 4th generation (4G) communication system such as long-term evolution (LTE). An antenna module in a wireless communication system includes: a printed circuit board (PCB); a radio frequency integrated circuit (RFIC); and a plurality of antenna elements for emitting a radio frequency (RF) signal, wherein the plurality of antenna elements may be disposed in a first area of a first surface of the PCB, and the RFIC may be disposed in a second area, different from the first area, of the first surface of the PCB.

    摘要: Parabolic reflector antennas advantageously support low side lobe radiation patterns for ETSI class 4 performance, by utilizing: (i) metal choke plates adjacent a distal end of a dielectric cone within a sub-reflector assembly, (ii) “lossy” material feed boom waveguide sleeves and/or (iii) extended length cylindrical shields lined with radiation absorbing materials. Relatively shallow and large diameter parabolic reflectors having an F/D ratio of greater than about 0.25 may be provided with one or more of the identified (i)-(iii) enhancements.
