Multi-frequency miniaturized folding monopole antenna of loaded grounding LC structure

Abstract

The invention discloses a multi-frequency miniaturized folding monopole antenna of a loaded grounding LC structure. The antenna comprises a rectangular dielectric substrate. A rectangular metal grounding plate is arranged at an edge of a lower surface of the rectangular dielectric substrate, a rectangular metal radiation arm is arranged at the edge of an upper surface of the rectangular dielectricsubstrate, a first horizontal metal arm connected with the rectangular metal radiation arm is arranged at a tail end of the rectangular metal radiation arm, and a wood comb cross structure connectedwith the first horizontal metal arm is arranged at the tail end of the first horizontal metal arm. The wood comb cross structure is composed of a plurality of horizontal metal arms arranged at intervals and two vertical metal arms. The horizontal metal arms are successively and alternately connected with the vertical metal arms on the two sides to form two wood comb structures. A lower surface ofthe rectangular dielectric substrate is provided with a second horizontal metal arm, and the second horizontal metal arm is connected with the vertical metal arm of the wood comb structure through a rectangular metal via hole. A vertical grounding metal arm is arranged at the tail end of the second horizontal metal arm and is connected with the rectangular metal grounding plate. In the invention,four frequency bands of four resonant frequency points can be realized, and miniaturization of the antenna is realized.

Description
