    摘要: The invention discloses a hybrid compact, near-field-to-far-field and direct-far-field test system in an anechoic chamber. It comprises a curved reflector with its primary feed antenna set situated on a lateral side and pointing towards it, a secondary feed antenna set pierced to the reflector or in front of it, and one or several sets of antennas or devices under test (AUT/DUT), and their 3D turntable tower placed at a quiet zone, for which roll, elevation and azimuth can change. In a receive process, the primary antenna set transmits several signals towards the reflector, which reflects these signals towards the quiet zone in the form of planar wavefronts. The secondary antenna set also transmits several signals, but directly towards the quiet zone in spherical wavefronts. The AUT/DUT receives all these signals simultaneously. Through reciprocity, a similar measurement process for transmission can be performed.

    摘要: A testing system may include a test electronic device having a test antenna disposed in a first signal path of a first antenna array of an electronic device. The test antenna may receive a first signal from the first antenna array. The testing system may also include a reflector disposed in a second signal path of a second antenna array of the electronic device. The reflector may reflect a second signal from the second antenna array to the test antenna. The reflector may include a flat, parabolic, or elliptical curvature that reflects a radio frequency signal emitted by the second antenna array to the test antenna.

    摘要: A computer assisted method for manufacturing a foldable paraboloid antenna includes election of a two-dimensional radial Origami pattern with triangular cells and election of a paraboloid surface. The Origami pattern is projected from the paraboloid surface focus onto the paraboloid surface to print the Origami pattern on the paraboloid surface, obtaining triangles with curved sides. A pattern with triangles with straight sides on the paraboloid surface is obtained by joining vertices of the projected curved-sided triangles. The method includes scaling and calculating centroids of the triangles, to reduce each triangle referenced on the corresponding centroid and to determine spacing, obtaining a mesh with segments and triangular cells delimited by the segments. The triangular cells have triangles of reflective rigid material. The mesh is flexible, so each segment width is at least the sum of the thicknesses of two adjacent rigid triangles, and periphery cells have a rounded outer edge.

    摘要: The present invention relates to an antenna RF module, an RF module assembly, and an antenna device including same. Particularly, the present invention comprises an RF filter which has at least four outer side surfaces, a radiation element module which is disposed on one surface of the outer side surfaces of the RF filter, an amplifier substrate which is disposed on another surface of the outer side surfaces of the RF filter and on which an analogue amplification element is mounted, and a reflector which is disposed between the RF filter and the radiation element module to ground (GND) the radiation element module and also mediate the outwardly dissipating heat generated by the RF filter, wherein socket pins are coupled to a main board disposed at an antenna housing in a unit of a module. Accordingly, a radome which hinders heat dissipation toward the front of the antenna is not needed and heat generated by heating elements of the antenna device is spatially separated so that the distributed heat dissipation toward the front and rear of the antenna device is possible, thereby remarkably improving heat dissipation performance.
