SLOT ANTENNA USING RESONANT FEED STRUCTURE

WIPO Patent Application WO/2016/041486

A1

Proposed is a slot antenna using a resonant feed structure, comprising: a slot, a resonance circuit and a connecting line; the slot being formed by surrounding with a metal frame and a ground potential metal plate; the resonance circuit comprising a series resonance circuit, with one end of the series resonance circuit being connected to the metal frame via the connecting line, and the other end thereof being connected to a feed potential of the ground potential metal plate via the connecting line; and the series resonance circuit comprising a capacitor and a matching element, wherein the matching element is any one or a combination of some of a capacitor, an inductor or a conducting wire. The present invention realizes a mobile phone construction whereby the metal frame is continuous in characteristics, reduces a break-joint process and an injection-molding process during traditional mobile phone manufacturing, and also improves aesthetics; and at the same time, high-quality signal radiation performance of a metal mobile phone antenna is ensured.
