Referring to Fig. 1, it is a schematic diagram of a conventional wireless communication device la. At present, in order to improve the above situation, the housing 12a must have a non-metal portion '22' and a metal portion 124a. The non-metal portion 122a may be made of a non-metal material such as plastic or carbon fiber, so that electromagnetic waves can pass through the non-metal portion 122a, and can be received by an antenna (not shown) provided in the casing 12a, or the antenna radiation = electromagnetic wave. It can be radiated through the opening of the non-metal portion 122a. Please refer to Fig. 2 for a schematic view of U.S. Patent No. 20,100,141,535. The field pattern and the average gain of the antenna 26a in the casing 22a are lifted by a metal piece 24a disposed on the casing 22a of the electronic device 2a. However, the metal piece 24a must be prevented from excessively overlapping with the antenna 26a, otherwise the effect of increasing the antenna gain will not be achieved, and the shielding effect described above will be caused. 3 [New content] Yes, the main purpose of the present invention is to provide an antenna structure and an electronic device suitable for solving the problems of the prior art. , an optical antenna structure is disposed on a substrate, and a metal plate is wrapped. The radiation unit is disposed on the substrate. The radiating element contains a grounding. The radiation department uses tons of radiation - electromagnetic waves. One end of the grounding part is connected The other end is electrically connected to the ground. The metal plate contains - a hole, and the electrical connection causes the breakage of the early 70 - the miscellaneous, the rib is excited by the radiating element. The embodiment also proposes an electronic device comprising a casing and an antenna fortune, including a substrate, a unit and a metal plate. . The ttit ί radiation unit includes a radiating portion and a grounding portion. Radiation ^ is used to shoot an electromagnetic wave. The grounding portion is electrically connected to the ground.

The hole is spaced apart from the radiating element by a distance for excitation by the radiation early element to produce at least one resonant mode. = The new version of this _ ' can increase the gain of the radiation material, increase the bandwidth or taste: modal. And when applied to the outer casing of an electronic device, the electronic device can be made to have an aesthetically pleasing metal casing' and the gain of the radiating element can be avoided. [Embodiment] _ π Referring to Figs. 3 and 4, respectively, is a schematic view and a side view of a first embodiment of the present invention. The antenna structure is disposed on the substrate 12 and includes the early element 14 and the metal plate 16. The radiation unit 14 is disposed on the substrate 12. The radiating element 14 includes a radiating portion 141, a ground portion 143, and a feed point 145 therebetween. The radiating portion 141 is configured to receive the feed signal at the feed point 145 to radiate the electromagnetic wave. The grounding portion 143 is connected at one end to the radiating portion 141' and the other end is electrically connected to the ground. The metal plate 16 includes a hole 162' and is electrically connected to the ground. Thereby, the metal plate % can be excited by the radiation unit μ M417671 to generate at least one resonance mode. > The secret refers to the electricity and electricity _ reference reference point. That is, the metal plate 16 and the radiating element 14 can be connected to the same grounding ground to two grounding grounds. Among them, the two grounding wires can be separated by isolation elements such as sense and wire, and the ribs are higher than the circuit or the strong circuit. package

Therefore, the quality of the radiation unit 14 can also be improved. On the other hand, when the electromagnetic wave is received, the panel 16 is used to couple the electromagnetic wave signal to the radiating element 14 and convert it into a number. The metal plate 16 provides a larger area to receive electromagnetic waves '^ for improved lifting. It should be noted that the hole 162 and the radiating element 14b = the distance d apos are prevented from being too far apart to couple the electromagnetic wave signal; or, the distance is too close, so that the radiated electromagnetic wave surface exceeds the standard. Here, in FIG. 3, the broken hole 162 may be in the form of "u,", but the present invention is not limited thereto. The shape of the hole 162 may also be a circular, square, or other geometric shape, or other irregular shape. For example, the hole 162 can be designed as a trademark pattern.
