Abstract
An antenna radiates signals in Band41 whose center frequency is λ1 and Band42 whose center frequency is λ2. A medium substrate is used as a carrier of a top radiating element, a phase inversion unit, and a bottom radiating element; an end of the top radiating element is connected to an end of the phase inversion unit; the other end of the phase inversion unit is connected to an end of the bottom radiating element, a length of the phase inversion unit is 3λ2/2, and the length of the phase inversion unit is greater than λ1/2; and the phase inversion unit includes at least two current phase inversion points, a part between the at least two current phase inversion points does not produce radiation, and the top radiating element and the bottom radiating element horizontally radiate the signal in the Band41 and the signal in the Band42 omnidirectionally.
