Abstract :
Shippsilas HF loop antenna with capacitative load is optimized for NVIS link with application of method of moments. Optimizing criteria for electric current distribution on antenna structure is set by means of greater power radiation of linear horizontal polarization wave in zenith direction. Starting values for capacity load of loop antenna is given by equivalent two-wire transmission line analysis. Optimized shippsilas loop antenna has appropriate properties for NVIS radio communication.
