Antenna gain of folded rhombic antenna for transient electric-field measurements

摘要

A folded rhombic antenna as a broadband antenna for measuring a transient electromagnetic field was designed so that its dimensions were reduced as 1/2 smaller than the original antenna. Antenna gains of their antennas were measured by the 3-antenna method. As a result, a usable frequency range of the antennas is from 400 MHz to 4.8 GHz.
