Due to everyone's unanimous advocacy of lightness and smallness, limited internal space, insufficient antenna height area (the antenna height is usually less than 3mm), and a full metal back shell, these wireless communication terminals are no longer suitable for Monopole antennas, nor are they suitable for conventional PIFAs. Antenna Form to Design Antenna
But when the wavelength corresponding to the center frequency is relatively large (for example, the half wavelength of the center frequency of WIFI 2.45GHz will take about 60mm), on the one hand, the wireless communication terminal does not necessarily have such a long space, and the self-resonance of the antenna cannot be achieved. Requirements; on the other hand, the slots with larger lengths occupy a large area on the housing of the wireless communication terminal, which greatly affects the appearance of the product

Embodiment Construction
[0027] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0028] Such as Figure 1 to Figure 3 As shown, a folded slot 20 antenna includes a radiation plane 10, the radiation plane 10 is provided with a folded slot 20, and the radiation plane 10 is provided with a ground feed point 31 and a signal feed point 32. The folded slot 20, the ground feed point 31 and the signal feed point 32 are integrated with the radiation plane 10, and the folded slot 20 adopts a square-wave folded or "S"-shaped zigzag. 20. The total length of the folded slot 20 is about half of the wavelength of the center frequency of the used frequency band. Obviously, the total length of the foldable slot 20 is not limited to this value, and the actual total length needs to be slightly adjusted according to the environment of the wireless communication terminal and the width of the slot. The ...

The invention discloses a folded slot antenna, which comprises a radiation plane, a folded slot is arranged on the radiation plane, and a ground feeding point and a signal feeding point are arranged on the radiation plane. The invention makes full use of many characteristics of the slot antenna, such as low profile, light weight, simple processing, easy to conform to objects, easy to mass produce, and easy to diversify electrical properties, etc., combined with the slot, the folding and bending method is adopted to realize the miniaturization of the antenna area , can be completely conformal with the casing, the performance of the antenna has been greatly improved, and it has the advantages of simple structure, beautiful appearance, and low cost. The invention can be widely applied to the antenna design of various wireless communication terminals.
Description
technical field [0001] The invention relates to antennas, in particular to a folded slot antenna. Background technique [0002] Slot antenna: An antenna formed by slits on a conductor surface, also known as a slot antenna. [0003] In recent years, the metal casings of wireless communication terminals such as tablet computers and smart phones have attracted the attention of the public and become a trend. There has been an upsurge in the market to develop wireless communication terminals with all-metal casings. Due to everyone's unanimous advocacy of lightness and smallness, limited internal space, insufficient antenna height area (the antenna height is usually less than 3mm), and a full metal back shell, these wireless communication terminals are no longer suitable for Monopole antennas, nor are they suitable for conventional PIFAs. antenna form to design the antenna. Even if an antenna is barely designed in this type of wireless communication terminal in the form of PIFA,...
