ANTENNA Russian patent published in 2023 - IPC H01Q1/36 H01Q13/08 

FIELD: radio engineering.

SUBSTANCE: receiving and transmitting shielded antennas of eddy-free non-polarized scalar-longitudinal electromagnetic waves in the microwave range. The receiving and transmitting antenna contains an input three-dB divider 2, a two-channel mutual phase-shifting unit 7, consisting of blocks of the reference channel 8 and anti-phase channel 9, the mode-field-wave inventory 14 in the form of a metal quasi-stationary cavity resonator 15 in the form of a sector of a circle, inside of which there are synchronization blocks of the reference channel 17 and antiphase channel 18, connected to a two-channel geometric vector converter 20, the output of which is connected to the block of field-wave interference zero-vector summation 26, the output of which is connected to the block trap-absorber 29, connected to a monopole antenna 33, located in a metal cone-shaped reflector 30 with a screened aperture in the form of a metal plug 31.

EFFECT: creation of a receiving and transmitting screened monopole antenna, which, when emitted, converts the input vortex transverse-vector electromagnetic field of a TEM wave into an irradiated eddy-free scalar-longitudinal electromagnetic field, and in the receive mode it operates in the reverse order.
