摘要： A method (200) of over-the-air testing of a transmission equipment (20). The method comprises transmitting (202) a transmission signal from the transmission equipment. The transmission signal as transmitted comprises emissions in an in-band domain (102) and emissions in an unwanted domain (110). The method comprises arranging a frequency selective surface (40) to receive the transmission signal. The frequency selective surface (40) attenuates the transmission signal in the in-band domain (102) of the transmission signal. The frequency selective surface (40) allows propagation of the transmission signal in the unwanted domain (110) of the transmission signal. The method further comprises measuring (206) in a measuring equipment (25) a parameter of the transmission signal in the unwanted domain. The frequency selective surface (40) is arranged between the transmission equipment (20) and the measuring equipment (25).

摘要： A substrate integrated waveguide, SIW, antenna comprises a modified design of prior art SIW antennas that comprises an addition of electrically conducting means, e.g. vias, also along the substrate extending from the antenna aperture. By doing so, the SIW antenna of the present disclosure enables a reduction of mutual coupling between neighboring SIW antennas when arranged adjacent each other, e.g. in an array. Moreover, a reduction of back radiation in the SIW antenna can also be observed.

摘要： A filter for filtering an electromagnetic wave and a filter design method are provided. The filter comprises a cavity with a first plate and a second plate, the first and second plates are opposite to each other. The first plate comprises a number of elements distributed on the side of the first plate facing the cavity, wherein a location of each element on the first plate is defined in a coordinate system. The second plate comprises a number of elements distributed on the side of the second plate facing the cavity according to the locations of the elements on the first plate, wherein each element is distributed on the second plate with an offset with respect to a corresponding element on the first plate.

摘要： The embodiments herein relate to a method performed by a communication node (103) for enabling OTA testing. The communication node (103) comprises at least one active antenna (310). The communication node (103) transmits a test signal OTA by emitting a radiation pattern from the active antenna (310). The active antenna (310) scans two or more directions when emitting the radiation pattern.

摘要： An antenna device (1) and an antenna stack (20) comprising at least two antenna devices are disclosed. The antenna device comprises a leaky wave antenna structure comprising a waveguide structure (2) extending in a first plane along a first axis (101), wherein the waveguide structure comprises two opposite end portions (3) along the first axis, and a first feed point and a second feed point arranged at opposite end portions of the waveguide structure. The antenna device further comprises a dispersive lens structure (6) having an edge extending along the waveguide structure in the first plane, the dispersive lens structure having an extension along a second axis (102) extending in the first plane in a second direction perpendicular to the first axis. The waveguide structure further comprises a plurality of discontinuities along an interface between the waveguide structure and the dispersive lens structure for leaking electromagnetic energy into dispersive lens structure.
