Mobile terminal and multiband aerial used on same

Abstract

The invention provides a mobile terminal and a multiband aerial used on the same, belonging to the field of basic electric elements. The multiband aerial comprises a grounding part, a first radiation part and a first feed part arranged on the first radiation part, wherein the first radiation part comprises a first radiation arm and a second radiation arm, and the first radiation arm is formed by upwards extending from one side of the two opposite sides of the grounding part and is provided with at least one first gap; the second radiation arm is formed by extending from the side opposite to the jointing side of the first radiation arm and the grounding part, positioned on the same side of the first radiation arm together with the ground part and provided with at least one second gap; a plurality of gaps are arranged on the first radiation part of the multiband aerial to ensure that induction current generated by electromagnetic waves in the multiband aerial can flow through the first radiation part and can be coupled in the gaps on the first radiation part, thus a resonance structure with broadband characteristics can be formed to ensure that the resonance can work in multiband and has wider frequency band.

Description

technical field [0001] The invention belongs to the field of basic electrical components, and in particular relates to a multi-band antenna used on a mobile terminal and the mobile terminal. Background technique [0002] With the rapid development of mobile communication, people increasingly hope to be equipped with a notebook computer or other portable terminals so as to be able to access the Internet anytime and anywhere. At present, the communication standards of notebook network cards in the world at least include: WWAN (Wireless Wide Area Network) protocol, WLAN (Wireless Local Area Network) protocol and WiMax (Global Microwave Interconnection Access) protocol, wherein the wireless network of WWAN protocol works at 820-960MHz and The frequency range of 1710-2170MHz, the wireless network of WLAN protocol works in the frequency range of 2.45GHz and 5.15-5.85GHz, the wireless network of WiMax protocol works in the frequency range of 2.3-2.8GHz and 3.3-3.8GHz.
