specific Embodiment

[0038] (1) specific embodiment basic structure

[0039] Such as figure 1 and 2As shown, the metal frame (metal shell) of the present invention requires specific modification, and this modification is the key technology of the present invention. The specific modification plan is that directly below the primary radiation unit 1, part or all of the metal of the metal shell needs to include a hollow 10; the size of the hollow 10 is changed accordingly according to the form, position, and working frequency band of the antenna. The edge part of the metal shell 3 is close to the position of the primary radiation unit 1, and a gap 6 is appropriately opened. The size and position of the gap 6 can be adjusted according to the needs. The gap 6 should be directly connected with the hollow 10. This feature is different from other existing antennas. main features of . The slit 6 cuts the edge of the metal casing to form an opening in the ring shape of the casing, thereby forming a second...

Abstract

The invention relates to a built-in secondary radiating antenna. The antenna comprises: an antenna support; a primary radiating unit (1) on the support; a connection terminal of the primary radiating unit; and a secondary radiating unit; besides, the connection terminal of the primary radiating unit is electrically connected with a circuit board (2); and the secondary radiating unit, which is formed by a terminal metal casing (3), is coupled with the primary radiating unit and a resonance is jointly formed by the secondary radiating unit and the primary radiating unit on a working frequency; moreover, the terminal metal casing (3) consists of a hollowing (10) and / or a slit (6) and is electrically connected with a grounding terminal of the circuit board. According to the built-in secondary radiating antenna provided in the invention, a primary radiating unit and a secondary radiating unit form an integrated antenna; compared with a volume of a traditional built-in antenna, the volume of the built-in secondary radiating antenna is smaller; moreover, defects on a structure and an appearance of an all-metal frame antenna are avoided; and meanwhile, the antenna performance is excellent.

Description

technical field [0001] The invention relates to wireless communication, in particular to a built-in secondary radiation antenna, especially applicable to dual-mode or multi-mode mobile phones. Background technique [0002] With the development of wireless communication technology, especially in the current network society, wireless terminal equipment has become an indispensable tool for people's life and work. At the same time, the vigorous development of information technology makes the same wireless communication system equipped with more and more information subsystems. ; and the increase of the information subsystem will inevitably lead to the increase of antenna multi-band collection and antenna complexity. Looking at the wireless communication market, the thinness and miniaturization of handheld terminals are more favored by consumers in a highly competitive environment; and thin The trend of miniaturization will inevitably lead to smaller and smaller design space rese...
