Electric small-sized fractal monopole antenna

Abstract

The invention discloses an electric small-sized fractal monopole antenna (length-0.049. lamda c, width-0.041.lamda c, height-0.068.lamda c, and lamda c represents resonant frequency). The electric small-sized fractal monopole antenna is characterized by comprising a round metal floor and an aerial radiation body, wherein the aerial radiation body comprises radiation bodies respectively composed of circular-arc Gussie.Piano fractal curve conductors, a left inverted-L-shaped conductor section, a right inverted-L-shaped conductor section, a vertical cylindrical helix I connected to the horizontal middle section of the left inverted-L-shaped conductor section, a vertical cylindrical helix I connected to the horizontal middle section of the right inverted-L-shaped conductor section and horizontal circular rings connected to the two vertical cylindrical helixes. The left inverted-L-shaped conductor section and the right inverted-L-shaped conductor section are respectively connected with two fractal curve radiation bodies and are mutually symmetric, one circular-arc Gussie.Piano fractal curve radiation body is directly short-circuited to the metal floor, and the other circular-arc Gussie.Piano fractal curve radiation body is connected with a coaxial feeder. Ideal impedance matching, higher gain and good efficiency of the electric small-sized fractal monopole antenna are achieved, and the electric small-sized fractal monopole antenna has the advantages of being novel in concept, clear in principle, pervasive in method, easy to process and the like.
