Improvement of Broadband Folded Long-Hexagon Antenna for EMI Measurements

Abstract

In this paper, an improved folded long-hexagon antenna was introduced. The voltage standing wave ratio (VSWR), the complex antenna factor, and the absolute gain for the improved antennas were measured up to 40 GHz. These results show that the usable frequencies of the improved antennas were from 480 MHz to 40 GHz.
