US Patent 11342661 Antenna structure and wireless communication device using the same

An antenna and antenna module with a structure increasing radio wave coverage but reducing cross interference between modules includes a circuit board in the shape of an octagon and four antenna modules. The circuit board thus includes eight side surfaces, and the four antenna modules are respectively disposed on four non-adjacent side surfaces of the octagon. Each antenna module is electrically connected to the side surface by a feed portion. A wireless communication device using the antenna structure is also disclosed.
