Abstract

An enhanced printed circuit board monopole antenna includes a baseplate, a signal feed-in unit, a first-radiation unit, a second-radiation unit and an auxiliary ground unit. The first-radiation unit and the second-radiation unit are arranged on a front side and an edge side of the baseplate. The auxiliary ground unit is arranged on the edge side and electrically connected to a first ground unit and a second ground unit on the baseplate. Adjusting the first-radiation unit controls 88 MHZ-60 GHZ frequency range impedance, resonant frequency, bandwidth and radiation effect. According to the frequency wave length (1λ, ½λ, ¼λ or ⅛λ) formed by the first-radiation unit and the second-radiation unit cooperating with each other, controlling 88 MHZ-60 GHZ frequency range achieves the predetermined target impedance, resonant frequency, bandwidth and radiation efficiency. The antenna radiation efficiency can be increased effectively.
