A multi-frequency miniaturized folded monopole antenna loaded with a grounded lc structure

Abstract

A multi-frequency miniaturized folded monopole antenna loaded with a grounded LC structure includes a rectangular dielectric substrate, a rectangular metal grounding plate is arranged on the edge of the lower surface of the rectangular dielectric substrate, a rectangular metal radiating arm is arranged on the edge of the upper surface of the rectangular dielectric substrate, and the rectangular metal The end of the radiating arm is provided with a first horizontal metal arm connected to it, and the end of the first horizontal metal arm is provided with a wood-comb cross-type structure connected to it; the wood-comb cross-type structure consists of several horizontal metal arms and two vertical metal arms arranged at intervals The horizontal metal arms are alternately connected with the vertical metal arms on both sides to form two wooden comb structures; the lower surface of the rectangular dielectric substrate is provided with second horizontal metal arms, and the second horizontal metal arms pass through the rectangular metal vias and the wooden comb structure. The vertical metal arm is connected; the end of the second horizontal metal arm is provided with a vertical ground metal arm, and the vertical ground metal arm is connected to the rectangular metal ground plate. The invention can realize four frequency bands with four resonance frequency points, and realize the miniaturization of the antenna.

Description
