Waveguide with a Zigzag for Suppressing Grating Lobes
This document describes a waveguide with a zigzag for suppressing grating lobes. An apparatus may include a waveguide with a zigzag waveguide channel to suppress grating lobes in diagonal planes of a three-dimensional radiation pattern. The waveguide includes a hollow channel containing a dielectric and an array of radiation slots through a surface that is operably connected with the dielectric. The hollow channel has a zigzag shape along a longitudinal direction through the waveguide. The zigzag waveguide channel and radiation slots configure the described waveguide to suppress grating lobes in an antenna radiation pattern. This document also describes a waveguide formed in part by a printed circuit board to improve the manufacturing process.

Front-end modules with ground plane slots
An example radio frequency (RF) front-end module may include a printed circuit board (PCB) including a ground plane, an RF integrated circuit (RFIC) including RF components mounted on the PCB, and an antenna array on the PCB. The antenna array may operate at a first resonant frequency in a wireless communication network. Further, the RF front-end module may include a slot defined in the ground plane to provide a second resonant frequency in the wireless communication network. The second resonant frequency is lower than the first resonant frequency.
