Abstract :
In ionospheric vertical sounding, an antenna with 1 ~ 20 MHz detection frequency range is enough because F2 layer critical frequency is usually lower than 20MHz, and the antenna gain requirements are relatively low because of the strong vertical sounding echoes. Besides, stable impedance, and vertical main lobe of radiation in the whole sounding frequency range are also required. This paper presents a new type of antenna structure for ionospheric measurements. According to FEKO software simulation, it is optimal designed for the vertical ionospheric measurements with the miniaturized size.
