WIDEBAND AND DUAL-BAND N-ORDER MONOPOLE ANTENNA AND PRINTED CIRCUIT BOARD THEREOF

摘要

A wideband and dual-band n-order monopole antenna comprises an antenna body, a 5 GHz band matching branch, a 5 GHz band first-order branch, a 5 GHz band second-order branch, a 2.4 GHz band branch and a 2.4 GHz band matching branch. The antenna body is shaped substantially like an inverted “L,” including a first side and a second side, wherein the first side is substantially perpendicular to the second side. The 5 GHz band matching branch extends from the first side. The 5 GHz band first-order branch extends from the first side and in parallel to the 5 GHz band matching branch. The 5 GHz band second-order branch extends from the second side and is perpendicular to the 5 GHz band first-order branch. The 2.4 GHz band branch is connected to the second side through an extending arm, the combination of the extending arm and the 2.4 GHz band branch being shaped substantially like an “L.” The 2.4 GHz band matching branch extends outward from the second side.
