Abstract
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.
