Abstract

The present disclosure relates to a waveguide arrangement (1, 1') comprising a mounting printed circuit board (2), PCB, and at least a first waveguide layer (4). Each waveguide layer (3, 4, 5, 6) comprises at least a first waveguide conducting tube (7, 8, 9, 10, 11, 12), each waveguide conducting tube (7, 8, 9, 10, 11, 12) having an electrically conducting inner wall (13). The PCB (2) comprises a signal interface (14) for each waveguide conducting tube (7, 8, 9, 10, 11, 12). The waveguide arrangement (1, 1') further comprises at least a first coupling layer (15) that is positioned between the PCB and the first waveguide conducting tube such that at least the first waveguide conducting tube (7, 8, 9, 10, 11, 12) of the first waveguide layer (4) is connected to the corresponding signal interface (14) via the first coupling layer (15). Each coupling layer (15) comprises air passages (16, 16a, 16b) that enable air to pass through the coupling layer (15).

Description

technical field [0001] The present disclosure relates to a waveguide arrangement comprising a mounted printed circuit board (PCB) and at least a first waveguide layer. Each waveguide layer in turn includes at least a first air-filled waveguide, wherein each air-filled waveguide has a conductive inner wall. Background technique [0002] An antenna element is a device configured to transmit and / or receive electromagnetic signals (eg, radio frequency (RF) signals) for wireless communication. A phased antenna array is an antenna comprising multiple antenna elements with which the antenna radiation pattern can be controlled by varying the relative phase and amplitude of the signals fed to the different antenna elements. [0003] The practical realization of the signal filtering function of such antenna elements is a challenging task. High Q factors, multiple resonators, and high precision are required to achieve filters with low loss and strong rejection of frequencies near the...
