FIELD: electricity.
SUBSTANCE: due to usage of an upper load in the form of a round metal disc in the antenna design and optimisation of parameters of electric circuit of antenna matching, the specified increase of radiation efficiency is achieved.
EFFECT: increased efficiency of radiation by value of at least 6 dB in the band of lower frequencies of the working range with preservation of efficiency at medium and high frequencies.
