Comparing FIG. 12 with FIG. 3, and comparing FIG. 13 with FIG. 4, the biggest difference between the fifth embodiment and the first embodiment is as follows: in the fifth embodiment, the antenna carrying structure 1 can be a solid carrying structure without a through space, and the antenna carrying structure 1 has an outer surrounding surface 102, and a top surface 103 connected to the outer surrounding surface 102. More particularly, the first inner feeding structure 3 includes a first inner horizontal extending portion 31 disposed on the top surface 103 of the antenna carrying structure 1, and a first inner vertical extending portion 32 passing through the antenna carrying structure 1, and the second inner feeding structure 4 includes a second inner horizontal extending portion 41 disposed on the top surface 103 of the antenna carrying structure 1, and a second inner vertical extending portion 42 passing through the antenna carrying structure 1.

Beneficial Effects of the Embodiments

[0040] In conclusion, by virtue of “the inner surrounding radiation structure 2 being disposed on the antenna carrying structure 1”, “the first inner feeding structure 3 being disposed on the antenna carrying structure 1, and the first inner feeding structure 3 being surrounded by the inner surrounding radiation structure 2”, “the outer surrounding radiation structure 5 being disposed on the antenna carrying structure 1, and the inner surrounding radiation structure 2 being surrounded by the outer surrounding radiation structure 5 and separate from the outer surrounding radiation structure 5” and “the first outer feeding structure 6 being disposed on the antenna carrying structure 1 and corresponding to the first inner feeding structure 3”, the inner surrounding radiation structure 2 and the first inner feeding structure 3 can cooperate with each other to form a first antenna assembly S1 for generating a first antenna operating frequency, the outer surrounding radiation structure 5 and the first outer feeding structure 6 can cooperate with each other to form a second antenna assembly S2 for generating a second antenna operating frequency, and the first antenna operating frequency of the first antenna assembly S1 is greater than the second antenna operating frequency of the second antenna assembly S2.
