Abstract

Abstract

Background
As for the electromagnetic pulse (EMP) effect experiment in limited space or for large under test system, the inverted V-shaped biconical-wire grating antenna based on typical structure may not meet the requirements.
Purpose
In this paper, a novel horizontally polarized radiation-wave antenna deriving from the typical structure is proposed.
Methods
Firstly, local refinement strategy is used to reduce the field leakage on X axis near the center of the grating wires. In this way, the polarization component of the electric fields (E-fields) in this direction is enhanced and the field uniformity is improved at the same time. Secondly, the grating antenna is asymmetrically designed and the layout of typical biconical-wire grating antenna in +Y direction is adjusted so as to provide enough space for adjustment.
Results
Results show that the energy fed to the antenna can be redistributed by adjusting the layout of the wire grating antenna. Compared with the typical biconical-wire grating antenna, the polarized E-field component of the proposed antenna on X axis at (20 0 3.2) m is increased about 20% when the antenna is set up to 20 m, and a work range about 20 m×20 m is provided. Meanwhile, the polarized E-field components in +Y and 45° directions are reduced relatively fast. The E-field contour lines in +Y direction of the new antenna are gradually compressed and converged to the antenna’s convergence points, looking as a rugby.
Conclusions
The feasibility and validity of the presented scheme has been tested by antenna experiment, which also presents the characteristics of convenience for installation and maintenance.
