An arrayed antenna module includes a first antenna group, a second antenna group, a front conductive connecting assembly and a rear conductive connecting assembly. The first antenna group includes a plurality of first antenna structures arranged in parallel thereon. The second antenna group includes a plurality of second antenna structures arranged in parallel thereon. The front conductive connecting assembly includes a first front conductive connecting element electrically connected to the first antenna group, and a second front conductive connecting element electrically connected to the second antenna group. The rear conductive connecting assembly includes a first rear conductive connecting element electrically connected to the first antenna group, and a second rear conductive connecting element electrically connected to the second antenna group. Therefore, the arrayed antenna module provided can be applied to a portable electronic device so as to receive or transmit signals.
