A ball grid array (BGA) module integrated within a three-dimensional printed peanut-shaped lens is proposed for
high-data-rate wireless communications in the F-band (116–140 GHz) between a video camera and a TV or a laptop. The
module implements a 1 × 2 array antenna which radiates a wide beam in the horizontal plane (H-plane) and a narrower beam in
the vertical plane (E-plane). The dielectric lens, fabricated in ABS-M30 plastic, is a shaped lens designed to achieve a fan-beam
radiation pattern further narrowing the vertical plane and widening the horizontal plane of the BGA module. The realised gain of
the full antenna system is required to exceed 5 dBi within a 120° angular interval in the horizontal plane and a 20° angular
interval in the vertical plane. Measurements show a reflection coefficient below −9 dB from 116 to 140 GHz and a maximum
realised gain of 8.5 dBi at 130 GHz demonstrating feasibility of the cost-effective proposed design for a high-data-rate
