Patent attributes
An antenna module includes a parasitic unit and a first antenna unit. The parasitic unit includes a first parasitic radiation portion and a second parasitic radiation portion. The second parasitic radiation portion is electrically connected to the first parasitic radiation portion. The first parasitic radiation portion and the second parasitic radiation portion surround a central area. The first antenna unit includes a feeding terminal, a ground terminal and a first radiation portion, in which the ground terminal is electrically connected to a ground portion. The feeding terminal is configured to transmit and receive a first antenna signal. The first radiation portion is configured to collaborate with the parasitic unit to generate a first resonant mode. The first resonant mode includes a central frequency, a frequency twice of the central frequency and a frequency three times of the central frequency.
