The mutual impedances of two complex shaped wire dipole antennas placed near ground surface which are used for ultra wideband phased antenna array of the new Ukrainian low-frequency radio telescope “GURT” are numerically analyzed. All calculations were made with the electromagnetic modeling methods using the well-known NEC2 program based on the method of moments. The calculation results are presented as dependences of normalized mutual impedances and mutual radiation resistances on distance between radiators for different frequencies within 10–70 MHz.References
