[0002] The design direction of the current notebook computer is light, thin, small and short, and the screen also requires narrow frame or even frameless appearance. With the evolution of wireless technology, more and more antennas are needed, and the required size is also getting larger and larger, but the effective area available for the antenna is getting smaller and smaller, making the antenna design on the frame a big challenge. Further, the antenna is designed at the system port, and the metal ring antenna architecture is one of the main directions for future antenna design, but the distance between the metal ring antenna architecture and the frame (antenna clearance) will become smaller. Small antenna clearance will cause serious cross-talk between antennas, affecting the signal quality of the antenna and leading to poor signal. SUMMARY

In the embodiment of the present disclosure, by arranging the dielectric material unit on the frame 1, the wavelength length can be effectively shortened, the size of the metal ring in the antenna design can be effectively reduced, and then the overall size of the antenna can be reduced, the influence of insufficient system space on the antenna can be improved, and the space required for antenna radiation can be effectively shortened.
[0026] The present disclosure can effectively reduce the cost of large-area high-dielectric material by arranging the dielectric material unit opposite to the antenna mounting area.
[0027] The embodiment of the present disclosure can effectively reduce the wavelength required by the antenna by arranging the dielectric material unit on the frame 1, so as to improve the influence of small antenna clearance on the antenna.
[0028] Optionally, the dielectric material unit is detachably arranged in the mounting groove 2, and the dielectric material unit with the required coefficient can be selected according to different antennas, so as to accurately control the dielectric property of the antenna substrate and make the frequency bandwidth design of the antenna more convenient.

[0030] In some specific embodiments, the number of mounting grooves 2 is multiple, and one dielectric material unit is arranged in each mounting groove 2. The frame 1 has multiple mounting grooves 2, and each dielectric material unit is embedded in one of the multiple mounting grooves 2. Therefore, when the multiple mounting grooves 2 embed different dielectric material units, the dielectric properties of the substrate can be changed and controlled, and then the use frequency bandwidth of the antenna is affected. According to the needs, different dielectric material units can be arranged on the frame 1 to adjust the key frequency band.
