本文应用传输线理论分析法,确立一种电小天线(高度在λ/50～λ/25之间,长度在λ/4～λ/8之间)的基本设计原则,导出任意截面形状的天线导体的等效半径,提供了一种非园截面导体和介质材料一起塑压成形的新型电小天线的设计方法。 In this paper, the basic design principle of a small electric antenna (height between λ / 50 ~ λ / 25 and length λ / 4 ~ λ / 8) is established by theoretical analysis of transmission line. Antenna conductor with arbitrary cross section is derived Of the equivalent radius, provides a non-circular cross section of the conductor and the dielectric material with plastic forming a new type of small antenna design.
