Abstract (en)
[origin: EP4216367A1] This application provides an antenna, an antenna module, and an electronic device. The antenna includes a tapered slot antenna, a folded dipole, and a feeding structure. The tapered slot antenna includes a first metal structure and a second metal structure that form a tapered slot, and two ends of the tapered slot are a narrow-gap end and a wide-gap end. An extension direction of the folded dipole intersects with an extension direction of the tapered slot. The folded dipole includes a main dipole and a parasitic dipole that are disposed opposite to each other. The main dipole is located between the parasitic dipole and the narrow-gap end. The main dipole includes a first stub electrically connected to the first metal structure and a second stub connected to the second metal structure. An area between the main dipole and the parasitic dipole forms a resonant tank of the tapered slot antenna. The feeding structure is electrically connected between the first stub and the second stub, and feeds the folded dipole and the tapered slot antenna at the same time, to excite the tapered slot antenna that is a directional antenna and excite the folded dipole that is an omnidirectional antenna. This application has an advantage of dual-antenna miniaturization.
