Abstract

The invention discloses a double-rotational parabolic dipole antenna, which is used for solving of low gain caused by deviation of a main beam direction of the current standard radiation source antenna from a horizontal direction with different frequencies. The double-rotation parabolic dipole antenna comprises an upper oscillator, a lower oscillator and a connection device, wherein the outer surfaces of the upper oscillator and the lower oscillator are rotational paraboloids with same shape, the connection device comprises a coaxial connector, an inner conductor and an insulator, and the end surface of a second end of the insulator is conformal to the outer surface of the upper oscillator. As the typical embodiment of the invention, the exponential term coefficient of a rotational curvilinear equation of the rotational paraboloids is 0.06, the slope is 0.1, the radiation distance is 2 millimeters, and the maximum radius value of the upper oscillator and the lower oscillator is 48.5 millimeters. With the double-rotational parabolic dipole antenna disclosed by the typical embodiment of the invention, a horizontal omnibearing standard radiation field in a range of ultra wide band (1GHz to 18GHz) is achieved; and with the adoption of a mode of changing oscillator gap to a curve distance, the gain of the ultra wide band dipole antenna in the horizontal direction is enhanced.

Description

technical field [0001] The invention relates to the field of radio measurement, in particular to a standard radiation source antenna for RE102 comparison test and electromagnetic environment monitoring. Background technique [0002] The standard radiation source antenna is the transmitting antenna of the standard radiation source used in the RE102 comparison test, and is used to transmit ultra-wideband horizontal omnidirectional radiation signals. RE102 is a test experiment in the electromagnetic emission and sensitivity requirements of military equipment and subsystems. The frequency range of electric field radiation emission is 10kHz~18GHz (this design is designed for the high frequency band 1GHz~18GHz in the RE102 test). The standard radiation source antenna can also be applied to electromagnetic environment monitoring, shielding effectiveness test, normalized site attenuation measurement in anechoic room and site standing wave ratio measurement. The standard radiator an...
