Abstract

An assembly-type dual-band printed antenna may include a substrate, an antenna signal feed-in end, a first radiator, a substrate assembly and a second radiator. The antenna signal feed-in end may be disposed on the substrate. The first radiator may be disposed on the substrate and may be coupled to the antenna signal feed-in end. The substrate assembly may be installed on the substrate and may include a via hole. The second radiator may be disposed on the substrate assembly and may be coupled to the first radiator through the via hole.
