원통형 구조물이 결합된 광대역 소형 모노콘 안테나

초록

In this paper, an electrically small wideband monocone antenna with cylindrical structures is proposed. The proposed antenna consists of a monocone radiator with cylindrical and sub-cylindrical structures, a circular disk, and shorting pins connecting the circular disk and the ground plane. By attaching the shorting pins from the circular disk to the ground plane, the low-frequency band is expanded, and by attaching cylindrical and sub-cylindrical structures to the monocone radiator, the impedance matching characteristics in the middle-and high-frequency bands are improved. The proposed antenna was manufactured using a 3D printer to reduce the weight, and the surface of the antenna was coated by spraying the conductive point. The proposed antenna had a −10 dB impedance bandwidth ranging from 0.52 GHz to 2.22 GHz and a monopole-like radiation pattern.
