Abstract

The invention discloses a horizontal polarization nuclear electromagnetic pulse simulator antenna. The horizontal polarization nuclear electromagnetic pulse simulator antenna comprises an arc-shaped cage type line radiation dipole and further comprises two conical feed transition sections. The cage type line radiation dipole is composed of two arc-shaped cage type line radiation arms which are symmetrically arranged. Each cage type line radiation arm comprises a plurality of circular-ring-shaped supports and a plurality of radiation cables, wherein the circular-ring-shaped supports are sequentially fixed to form an arc-shaped framework of the cage type line radiation arm, and the radiation cables are evenly fixed along the outer edge of the framework. The two conical feed transmission sections are arranged between the two cage type line radiation arms and are symmetrically arranged. The bottom faces of the conical feed transition sections are fixedly connected with one ends of the inner sides of the two cage type line radiation arms respectively. The vertexes of the conical feed transition sections do not make contact. By means of the horizontal polarization nuclear electromagnetic pulse simulator antenna, radiation antennas of large nuclear electromagnetic pulse simulators can have better direction characteristics, and the pulse field intensity and the field uniformity of test areas are improved.

Description

technical field [0001] The invention belongs to the technical field of radiation antennas for nuclear electromagnetic pulse simulators, in particular to a horizontally polarized nuclear electromagnetic pulse simulator antenna. Background technique [0002] Simulating nuclear electromagnetic pulse radiation is a necessary means to carry out research on nuclear electromagnetic pulse effects and verification tests. Since the nuclear electromagnetic pulse has a wide spectrum and rich low-frequency components, the nuclear electromagnetic pulse radiation waveform according to the IEC standard ranges from a few kHz to GHz, and the main energy is concentrated below 300MHz, so a relatively large broadband antenna is required for radiation. There are many types of radiators for nuclear electromagnetic pulse simulators. Common ones include bounded wave simulators, vertical monopole simulators, horizontal dipole simulators, and composite simulators. Different types of radiators produce ...
