This paper proposes a simple. low-cost. and practical hybrid integration design of a 5G FR2 millimeter-wave antenna module based on a thin flexible printed circuit (FPC) and a 5G FR1 microwave antenna based on a metal frame to maximally save precious printed circuit board (PCB) space for more competitive 5G and beyond 5G (B5G) smartphones. The thin FPC-based millimeter-wave antenna mo... https://macorners.shop/product-category/wooden-car-visor-clip-friend-card/
