The results of electrodynamic modeling of a linearly polarized receiving antenna with an octave operating frequency range using the ANSYS HFSS software package are presented.

Purpose. Carry out numerical electrodynamic modeling [1,2] of the frequency characteristics of the receiving antenna of linear polarization [3] in the operating frequency range using the ANSYS R2 2019 software [4].

Results. The frequency characteristics of the linear polarization receiving antenna are presented. The VSWR of the receiving antenna in the operating frequency range does not exceed 2.6, the gain of the receiving antenna in the operating frequency range is not less than 6.0 dB. The frequency response of the module of the reflection coefficient of the linear polarization receiving antenna is not higher than -10 dB. The receiving antenna of linear polarization provides a scanning angle both in azimuth and in elevation, as part of an ultra-wideband digital antenna array [5,6] not less than ± 30 °.

Practical significance. It is shown that the considered receiving antenna of linear polarization in the operating frequency band, which is an octave, provides a VSWR value of no more than 2.6, CU not less than 6.0 dB.
