A Broadband Portable Three-Wire Antenna for Low-Power Vertical-Incidence Ionosonde

At present, almost all of the ionospheric sounders for the HF-band around the world are fixed. As a result the areas of sounding are restricted and the equipment cannot be fully exploited. After studying the design of the ionospheric vertical sounding antenna and the standard of parameter setting, a portable vertical sounding antenna based on portable single station ionospheric sounding system is designed that can be spanned easily. Compared to the traditional delta antenna and rhombic antenna, this one has the advantage of lower antenna height, smaller occupied area, smaller VSWR and better radiation performance, which achieves the broadband impedance and antenna pattern. The result suggests that this one is better than a conventional portable ionospheric VI sounding antenna.
